feat(settings): hub auth-policy panel — T4/T5 security parity in the GUI
Some checks failed
Security / Security check (push) Failing after 1s
Some checks failed
Security / Security check (push) Failing after 1s
Settings → Security now shows the hub's effective auth policy via the new read-only AuthStatus RPC: active token validator (static / jwt-rs256 with issuer, audience, JWKS source), anonymous-access warning, per-token cards with scope grants, env-var presence and rate limits, plus a localized admin-denied story for non-admin tokens. Live-reloads on endpoint change. Also fixes a batch of fai→chain rename leftovers this panel's verification uncovered: hub_auth_token.dart and registry_token.dart read/wrote ~/.fai/ while the hub reads ~/.chain/ (stored registry tokens never reached the hub), today_story_loader + tools/today used ~/.fai/today, chain_log legacy ~/.fai/logs migration removed per the no-legacy-recognisers decision, and UI strings still advertised the retired .fai bundle extension. Includes 5 widget tests for the panel, an integration-test screenshot harness (auth_policy_shots_test.dart, guide-shots style), and DE+EN l10n. flutter analyze clean, 58 tests green.
