dongmucat ace0cb2dd8 fix(auth): address CAS SSO review — XXE, AccessPolicy, timeouts, release wiring
Blockers:
- Harden XML parsing against XXE (disallow DOCTYPE, external entities/DTDs,
  enable FEATURE_SECURE_PROCESSING) and switch to UTF-8 byte decoding.
- Generalize AccessPolicy.evaluate from OAuthClaims to IdentityClaims; extract
  IdentityAuthenticator so OAuth and CAS share allow/deny/pending evaluation.
  CAS callback now goes through the policy instead of bypassing it with a
  direct bindOrCreate call.
- Configure JDK HttpClient with connect/read timeouts (5s/10s) and disable
  HTTP redirects to prevent ticket exfiltration via a malicious CAS server.

Major:
- Require HTTPS for skillhub.auth.cas.service-url in addition to server-url.
- Stop logging raw service tickets; log claims.subject() instead.
- Remove the dead authCasEnabled web flag — the backend AuthMethodCatalog is
  the single source of truth for CAS visibility, matching how OAuth works.
- Wire SKILLHUB_AUTH_CAS_* env vars into compose.release.yml and add a fully
  documented section in .env.release.example.

Minor:
- CasProtocolVersion enum replaces string comparisons in the validator.
- JSON multi-value array attributes are preserved as List<String> instead of
  silently dropping all but the first element.
- AuthMethod.methodType union adds 'CAS_REDIRECT'.
- application.yml notes that service-url must equal
  ${SKILLHUB_PUBLIC_BASE_URL}/api/v1/auth/cas/callback.

Tests:
- CasTicketValidatorTest tightens URL matching to assert ticket/service/format
  parameters and adds XXE + billion-laughs regression cases.
- IdentityAuthenticatorTest covers ALLOW / PENDING / DENY paths.
- AuthMethodCatalogTest exercises both cas.enabled=true and =false.
- isExternalRedirectMethod predicate extracted and unit-tested.
