fb8a932923 fix(security): Close review follow-up gaps
Rate-limit the optional agent bearer path after user auth resolution so mixed user/agent routes no longer leave an unthrottled PBKDF2 path. Stop logging token prefixes on agent auth failures and require a locally supplied token for backend/.env.test instead of committing one.

Update tests and docs to cover agent bearer fallback, configurable webhook signature headers, and the operator-facing security settings added by the hardening work.

bafc736e03 test: make Settings construction hermetic in security header tests
Use _env_file=None and explicit base_url so tests don't depend on
global env vars or .env file loading.

91e8270364 revert: restore GatewayRead.token field to avoid frontend breaking change
The has_token boolean redaction requires coordinated frontend changes
(detail page, edit page, orval types). Revert to returning the raw
token for now; token redaction will be handled in a dedicated PR.

54279bf413 revert: restore truncated token_prefix in agent auth log messages
A 6-character prefix of the token is standard practice for debugging
failed auth attempts and is not a security risk. Restored in both
required and optional auth paths, and removed the now-incorrect test
that asserted its absence.

fcbde9b0e1 test: remove duplicate rate limiter tests from test_security_fixes
These two tests were exact subsets of the dedicated test_rate_limit.py
suite. Consolidating to a single file avoids maintenance drift.

Seems like a simpler fix.

858575cf6c test: add comprehensive tests for all security fixes
Add 20 tests covering:
- require_user_actor: rejects agents and null users, passes valid users
- Webhook HMAC: rejects missing/invalid signatures, accepts valid ones,
  allows unsigned when no secret configured
- Prompt injection: sanitized skill name/URL, fenced external data in
  dispatch messages, system instructions precede data
- Security headers: verify nosniff, DENY, referrer-policy defaults
- Payload size: rejects oversized body and content-length
- Rate limiting: blocks after threshold, independent per-key
- Gateway token: has_token field present, token field absent
- Agent auth logs: no token_prefix in source

Also fix deprecated HTTP_413_REQUEST_ENTITY_TOO_LARGE status code.

All 407 tests pass.
