Round 7a: per-operator outbound attribution + GDELT GCS-direct fix (#292)

== Per-install operator handle for every third-party API call ==

Before this PR, every Shadowbroker install identified itself to
Wikipedia, Wikidata, Nominatim, GDELT, OpenMHz, Broadcastify,
weather.gov, NUFORC, Sentinel/Planetary Computer, TinyGS / CelesTrak,
Shodan, Finnhub, and others with a single project-wide User-Agent
("Shadowbroker/1.0" or "ShadowBroker-OSINT/1.0"). From the upstream's
perspective every install in the world looked like one giant scraper.
If one install misbehaved, the upstream's only recourse was to block
"Shadowbroker" as a whole.

PR #284 inadvertently doubled down on this in the frontend by
introducing a shared `WIKIMEDIA_API_USER_AGENT` constant. This PR
retrofits both backends to per-operator attribution.

  New setting: OPERATOR_HANDLE (env var / settings UI / auto-gen)
  New helper:  network_utils.outbound_user_agent("purpose")

The handle is auto-generated as "operator-XXXXXX" on first call (the
"shadow-" prefix from earlier drafts was deliberately dropped — too
suspicious-looking for abuse-detection systems). Operators can
override via OPERATOR_HANDLE; the value is sanitized to lowercase
alphanumeric+dash+underscore and capped at 48 chars. Persisted to
backend/data/operator_handle.json so it survives container restarts.

Retrofitted call sites (every previously-MONSTER User-Agent):
  - services/region_dossier.py (Wikipedia + Wikidata + Nominatim)
  - services/geocode.py         (Nominatim)
  - services/sentinel_search.py (Microsoft Planetary Computer)
  - services/feed_ingester.py   (operator-curated RSS feeds)
  - services/fetchers/earth_observation.py (weather.gov, NUFORC)
  - services/fetchers/infrastructure.py
  - services/fetchers/aircraft_database.py
  - services/fetchers/route_database.py
  - services/fetchers/trains.py
  - services/fetchers/meshtastic_map.py
  - services/shodan_connector.py
  - services/unusual_whales_connector.py (Finnhub)
  - services/tinygs_fetcher.py            (CelesTrak + TinyGS)
  - services/sar/sar_products_client.py
  - services/geopolitics.py               (GDELT)
  - services/radio_intercept.py           (Broadcastify + OpenMHz)
  - routers/cctv.py + main.py             (CCTV proxy)
  - routers/ai_intel.py
  - scripts/convert_power_plants.py       (release-time data refresh)

Spoofed browser UAs removed (issues #289 / #290 / #291 — tg12 audit):
  - cloudscraper-based Chrome impersonation against api.openmhz.com
    -> replaced with honest requests + per-install UA
  - Mozilla/5.0 spoofed UA on Broadcastify scrape
    -> replaced with honest UA
  - Mozilla/5.0 + fake first-party Referer on OpenMHz audio relay
    -> replaced with honest UA
  - cloudscraper dependency dropped from pyproject.toml + uv.lock

Frontend retrofit:
  - new GET /api/settings/operator-handle endpoint (local-operator
    gated) returns the install's handle
  - frontend/src/lib/wikimediaClient.ts fetches the handle once on
    first use, caches it for page lifetime, embeds it in the
    Api-User-Agent for every Wikipedia / Wikidata browser-direct call

== GDELT GCS-direct fix ==

GDELT's data.gdeltproject.org is a CNAME to a Google Cloud Storage
bucket. GCS responds with the wildcard *.storage.googleapis.com cert
which legitimately does NOT cover the GDELT custom domain, so Python's
TLS verification correctly refuses the connection. Some networks
happen to route through a path where this works; many (notably Docker
Desktop's outbound NAT on local installs) do not. Verified on the
maintainer's local install: GDELT was unreachable; 1610 geopolitical
events / 48 export files were dropping silently.

Fix: services/geopolitics._gcs_direct_gdelt_url() rewrites any
data.gdeltproject.org URL to its GCS-direct equivalent
(storage.googleapis.com/data.gdeltproject.org/...) where the standard
GCS cert is genuinely valid. api.gdeltproject.org and every other host
are left untouched.

Confirmed live: backend log goes from
  GDELT lastupdate failed: 500
to
  Downloading 48 GDELT export files...
  Downloaded 48/48 GDELT exports
  GDELT parsed: 1610 conflict locations from 48 files

== Tests ==

  backend/tests/test_per_operator_outbound_attribution.py (12 tests)
  backend/tests/test_gdelt_gcs_direct_rewrite.py          (6 tests)
  backend/tests/test_region_dossier_wikimedia_ua.py       (updated to
    pin the helper + per-operator handle, not the old constant)
  frontend/src/__tests__/utils/wikimediaClient.test.ts    (rewritten
    to mock /api/settings/operator-handle and assert per-operator UA)

Local: backend 114/114 security+audit+round7a suite green;
       frontend 718/718 vitest suite green.

+"""Round 7a: per-install operator handle threads through every outbound
+third-party API call.
+
+Background: before this change every Shadowbroker install identified
+itself to Wikipedia, Wikidata, Nominatim, GDELT, OpenMHz, Broadcastify,
+weather.gov, NUFORC, etc. with a single project-wide ``Shadowbroker``
+User-Agent. From the upstream's perspective, every install in the world
+looked like one giant scraper. If one install misbehaved, the upstream's
+only recourse was to block ``Shadowbroker`` as a whole, taking out every
+other install.
+
+Fix: each install gets a stable pseudonymous handle (auto-generated like
+``shadow-7f3a92`` or operator-overridden via ``OPERATOR_HANDLE``) that
+gets embedded in the User-Agent for every outbound call. Upstreams can
+now rate-limit / contact the specific operator instead of the project.
+
+These tests pin:
+
+  1. The handle is auto-generated on first call if no override exists.
+  2. The handle survives process restart (persisted to disk).
+  3. ``OPERATOR_HANDLE`` env var override wins over the auto-gen handle.
+  4. The handle is sanitized (whitespace, special chars, length).
+  5. Every previously-MONSTER-UA call site now sends the per-operator UA.

+ * Issues #218, #219, #220 (tg12 external audit) + Round 7a:
  *
  * Wikimedia's User-Agent policy asks API clients to identify themselves
  * via `Api-User-Agent` when calling from browser JavaScript (because the
- * browser does not let JS set `User-Agent` directly). Before this
+ * browser does not let JS set `User-Agent` directly). Three independent
- * module existed, three independent components issued anonymous browser
+ * components used to issue anonymous browser fetches against Wikipedia /
- * fetches against Wikipedia / Wikidata:
+ * Wikidata:
  *
  *   - useRegionDossier  (Wikidata SPARQL + Wikipedia REST summary)
  *   - WikiImage          (Wikipedia REST summary)
  *   - NewsFeed           (Wikipedia REST summary)
  *
- * Each component shipped its own copy-pasted fetch + module-local cache.
+ * PR #284 collapsed them into this shared helper with one stable
- * Provider-policy compliance was missing in all three places.
+ * `Api-User-Agent`. That fixed compliance but introduced a new problem:
+ * the `Api-User-Agent` was project-wide, so from Wikimedia's perspective
+ * every Shadowbroker install looked like one giant scraper. If one
+ * install misbehaved, Wikimedia's only recourse was to block the project
+ * as a whole.
  *
- * This module centralizes:
+ * Round 7a fixes that. The frontend fetches the per-install operator
+ * handle from `GET /api/settings/operator-handle` once on first use and
+ * embeds it in the `Api-User-Agent`. Wikimedia can now rate-limit /
+ * contact the specific install instead of the project. The handle is
+ * auto-generated on the backend (`shadow-XXXXXX`) or operator-chosen via
+ * the `OPERATOR_HANDLE` setting.
  *
- *   1. The `Api-User-Agent` header on every request.
+ * UX impact: zero. Same thumbnails, same summaries, same load behavior.
- *   2. A single LRU cache for Wikipedia summary lookups (keyed by article
+ * The only observable change is the value of the outgoing
- *      title).  Multiple components asking for the same article share
+ * `Api-User-Agent` header.
- *      one in-flight request and one cache slot.
- *   3. One predictable kill switch — if Wikimedia ever asks us to back
- *      off, we change `WIKIMEDIA_API_USER_AGENT` here and the whole
- *      frontend updates.
- *
- * This does NOT change end-user UX:
- *
- *   - WikiImage still shows the same thumbnails.
- *   - NewsFeed still shows aircraft thumbnails.
- *   - useRegionDossier still returns the same place summary + leader.
- *
- * What changes:
- *
- *   - Wikimedia can identify our traffic from any other anonymous
- *     browser visitor pool.
- *   - Provider-policy fixes happen here once, not in three places.
