fix(security): W4-E1 approvals admin-session only, shared redact table, TMDB key redaction, prod mock gate

- POST /approvals and PATCH /approvals/{id} require a console admin session
  (EndpointDef auth:"session"); API keys incl. admin scope get 403, so an
  organize.execute key can no longer approve its own plan (S1)
- tests for single-use approval checks: expired, revision/payload hash
  mismatch, consumed, revoked, pending/rejected, plan mismatch; re-approve
  after plan change succeeds once and cannot be replayed (S4)
- one redact key table in @umt/contracts shared by server logger and agent
  redactForModel: rsskey, torrent_pass, authkey, downhash, c_secure_pass,
  passkey variants, x-api-key, cookie headers, nested objects/arrays (S2)
- TMDB network errors: message and cause redacted via redactUrl (S3)
- web Agent ?mock=1 only in DEV builds or when pi.provider is fake (S7)
- EndpointDef auth annotations for /auth/*, asserted against
  PUBLIC_AUTH_PATHS (S10); doc drift fixes (S11)
