"""Issues #243, #252, #253 (tg12): settings endpoints must not leak
operational posture to unauthenticated callers.

- **#243**: ``GET /api/settings/wormhole``, ``/api/settings/privacy-profile``,
  and ``/api/settings/node`` were leaking transport choice, anonymous-mode
  state, the named privacy profile, and node-participant state to any
  unauthenticated caller. The fix tightens the redaction allowlists to
  expose ONLY a bare "is this feature on?" boolean and gates node mode
  behind authenticated reads.

- **#252**: ``GET /api/settings/news-feeds`` returned the operator's full
  curated feed inventory (names + URLs) to anyone. Now gated on
  local-operator.

- **#253**: ``GET /api/settings/timemachine`` returned whether archival
  capture is enabled to anyone. Now gated on local-operator.

Auth model: ``require_local_operator`` allows loopback (Tauri shell),
the Docker bridge frontend container (via the hostname-bound trust from
PR #278), and any caller that presents the configured admin key.
Anonymous LAN or internet callers do NOT pass and either receive 403
(news-feeds, timemachine) or a redacted minimum (wormhole / node).
