Fix #302: split OpenClaw HMAC reveal into dedicated POST with no-store

Reported by @tg12. Pre-fix, two problems lived on the GET endpoint:

  1. `GET /api/ai/connect-info?reveal=true` returned the full HMAC
     secret in the response body on every Connect modal open. Even
     gated to require_local_operator, that put the secret into
     browser history, dev-tools network panels, browser disk caches,
     HAR exports, and screen captures.

  2. The same GET endpoint auto-bootstrapped (generated + persisted)
     the secret on a mere read. Side effects on a GET are a footgun:
     browser prefetchers, mirror tools, and casual curl-from-history
     would all silently mint+persist a fresh secret.

Backend (backend/routers/ai_intel.py)
-------------------------------------
  GET  /api/ai/connect-info             — always returns the MASKED
                                          fingerprint (first6 + bullets
                                          + last4). No `?reveal` param.
                                          NO auto-bootstrap. When the
                                          secret is missing, returns
                                          `hmac_secret_set: false` and
                                          tells the caller to POST to
                                          /bootstrap.
  POST /api/ai/connect-info/bootstrap   — NEW. Mints+persists the secret
                                          if missing. Idempotent. Never
                                          returns the full secret in the
                                          response body.
  POST /api/ai/connect-info/reveal      — NEW. Returns the full secret
                                          with Cache-Control: no-store,
                                          no-cache, must-revalidate +
                                          Pragma: no-cache + Expires: 0.
                                          POST so the body never lands
                                          in URL history. 404 (with a
                                          pointer to /bootstrap) when
                                          the secret isn't set.
  POST /api/ai/connect-info/regenerate  — keeps existing one-time-reveal
                                          behavior (regen IS a deliberate
                                          destructive action triggered
                                          by the operator). Same
                                          no-store/no-cache headers added
                                          so even the regen response
                                          doesn't get cached.

Frontend (AIIntelPanel.tsx, OnboardingModal.tsx)
------------------------------------------------
  * On mount: GET (masked only). If hmac_secret_set: false, fire a
    transparent POST /bootstrap and refresh the masked fingerprint.
    Operator sees no behavior change from pre-#302.
  * Reveal (eye icon): lazy POST /reveal — secret only travels when
    the operator explicitly clicks the button.
  * Copy: lazy POST /reveal too — copying without a prior reveal
    works exactly like before, just routed through the new endpoint.
  * Regenerate: POST returns the new secret (same as before, but the
    response now has no-store headers).
  * The displayed snippet uses the masked fingerprint until the
    operator clicks Reveal or Copy.

Tests (backend/tests/test_openclaw_connect_info_reveal.py — 13 tests)
---------------------------------------------------------------------
  * GET returns masked + the full secret never appears in r.text
  * GET does NOT auto-bootstrap when missing
  * GET silently ignores any ?reveal=true query (back-compat noise)
  * POST /bootstrap mints when missing, idempotent when set
  * POST /bootstrap never returns the full secret
  * POST /reveal returns the full secret with Cache-Control: no-store,
    no-cache + Pragma: no-cache + Expires: 0
  * POST /reveal 404s with a pointer to /bootstrap when no secret
  * POST /regenerate returns the new secret with the same headers
  * Anonymous remote callers get 403 on ALL FOUR endpoints (parametric
    regression against the same allowlist used elsewhere).

Adjacent suites still green: test_openclaw_route_security,
test_no_new_duplicate_routes, test_control_surface_auth. 67/67 pass
locally.

+"""Rate-limit key function for slowapi.
+
+Issue #287 (tg12): the previous implementation used
+``slowapi.util.get_remote_address`` which only ever returns
+``request.client.host``. Behind the bundled Next.js proxy (or any other
+reverse proxy), every connected operator's ``client.host`` is the
+frontend container's bridge IP. ``@limiter.limit("120/minute")`` then
+collapses into one shared bucket for everybody on the same backend —
+one heavy tab can starve every other operator on the node.
+
+This module replaces that key function with one that:
+
+  * Reads ``X-Forwarded-For`` ONLY when the immediate peer is a trusted
+    frontend container (same allowlist used by the Docker bridge
+    local-operator trust path — see ``backend/auth.py`` ``#250``).
+  * Picks the FIRST entry in the XFF chain. That's the client end of
+    the proxy chain, which is the operator we want to bucket on.
+  * Falls back to ``request.client.host`` for any peer that isn't on
+    the trusted-frontend allowlist. Direct hits, unrelated containers,
+    and unknown hosts are bucketed exactly like before — there is no
+    way for an untrusted caller to spoof XFF and steal another
+    operator's rate-limit bucket.
+
+Single-operator nodes are unaffected: the frontend resolves to one IP,
+that IP is on the trust list, the XFF header is read, and you get one
+bucket per operator (i.e. you).

+"""USNI News Fleet & Marine Tracker — authoritative weekly carrier
+position publication.
+
+Why this exists
+---------------
+The previous carrier_tracker pipeline relied on GDELT headline matching
+(``api.gdeltproject.org``) to derive positions from text like "USS Ford
+in the Mediterranean" → centroid of "Mediterranean Sea". That was
+- low-precision (audit issue #245 — false precision from text mentions),
+- unreliable (``api.gdeltproject.org`` is sometimes unreachable from
+  certain network paths, including Docker Desktop on some Windows hosts).
+
+USNI publishes a weekly tracker that explicitly lists where every U.S.
+carrier is operating. The article body uses extremely consistent phrasing:
+
+    "The Gerald R. Ford Carrier Strike Group is operating in the Red Sea"
+    "Aircraft carrier USS George Washington (CVN-73) is in port in
+     Yokosuka, Japan."
+    "USS Dwight D. Eisenhower (CVN-69) sails down the Elizabeth River"
+
+Those are deterministic to parse. This module:
+
+  1. Pulls the WordPress RSS feeds (both site-wide and category) — the
+     site-wide feed often has fresher posts before the category feed
+     catches up, so we union them.
+  2. Picks the most recent post by parsed ``pubDate``.
+  3. For each carrier in the registry, scans the article body for a
+     "is operating in / is in port in / departed from" pattern near
+     the carrier's name.
+  4. Maps the extracted region phrase to coordinates via the carrier
+     tracker's existing REGION_COORDS.
+
+The result is a ``{hull: position_entry}`` dict that the carrier tracker
+consumes as a high-confidence source — ``position_confidence: "recent"``
+with ``position_source_at`` set to the article's actual publication
+timestamp (not ``now()``).
+
+Politeness
+----------
+We send the per-install operator handle via ``outbound_user_agent``
+(Round 7a) so USNI can rate-limit / contact the specific install if
+needed. Article-body pages return 403 to non-browser UAs (Cloudflare),
+but WordPress RSS feeds are open and serve the full article in
+``<content:encoded>`` — that's the supported path for aggregators and
+the one we use. We do not spoof browser headers.

+"""Issue #302 (tg12): OpenClaw connect-info HMAC secret disclosure.
+
+Before this change, ``GET /api/ai/connect-info?reveal=true`` returned the
+full HMAC secret in the response body on every modal open AND the same
+GET endpoint auto-bootstrapped (generated + persisted) the secret on a
+mere read. Even gated to ``require_local_operator``, that put the full
+secret into:
+
+  * browser visit history
+  * dev-tools network panel
+  * browser disk cache
+  * HAR exports
+  * screen captures / shoulder-surfing
+
+Every single time the OpenClaw Connect modal opened.
+
+After this change:
+
+  GET  /api/ai/connect-info            — always returns the MASKED
+                                          fingerprint. No ?reveal param.
+                                          No side effects (auto-bootstrap
+                                          gone).
+  POST /api/ai/connect-info/bootstrap  — mints+persists the secret if
+                                          missing. Idempotent. Never
+                                          returns the full secret.
+  POST /api/ai/connect-info/reveal     — returns the full secret with
+                                          strict Cache-Control: no-store
+                                          headers. POST so the body
+                                          doesn't land in URL history.
+  POST /api/ai/connect-info/regenerate — keeps the one-time-disclosure
+                                          for the new secret (regen IS a
+                                          deliberate destructive action).
+                                          Same no-store headers added.

+"""Issues #299, #300, #301 (tg12): Sentinel proxy routes must require
+local-operator auth.
+
+Before the fix, three Sentinel proxy routes in ``backend/routers/tools.py``
+were decorated only with ``@limiter.limit(...)`` — no
+``Depends(require_local_operator)``:
+
+  * ``POST /api/sentinel/token``  — Copernicus CDSE OAuth relay for
+    caller-supplied client_id + client_secret. Anonymous access made the
+    backend a free OAuth-mint relay for any Sentinel account.
+  * ``POST /api/sentinel/tile``   — Sentinel Hub Process API relay.
+    Caller supplies their own credentials, backend mints a token if
+    needed and relays the PNG. Anonymous access was a bandwidth + quota
+    relay for any Copernicus account.
+  * ``GET  /api/sentinel2/search`` — Planetary Computer STAC search with
+    Esri imagery fallback. No caller credentials are involved, but the
+    route is still an anonymous external-search relay.
+
+The fix adds ``dependencies=[Depends(require_local_operator)]`` to each.
+The parameterized regression in ``test_control_surface_auth.py`` covers
+the basic 403 path. This file adds the harder property: when the auth
+gate fires, **the underlying upstream HTTP call never happens** — no
+outbound Copernicus token mint, no Sentinel Hub Process call, no
+Planetary Computer STAC search. The egress-on-403 property is what
+separates a real gate from a route that returns 403 *after* burning a
