Integrated into release/v3.6.5. Added CHANGELOG breaking change entry for the removed /api/settings/codex-service-tier endpoint and deduplicated getCodexRequestDefaults in page.tsx (now imports from requestDefaults.ts).
Protect database backup, export, restore, and translator save endpoints
with authentication checks to block unauthenticated data access and
state changes.
Also remove the insecure API key secret fallback, ignore nested app env
files from package publishes, and align tests with explicit
application/json Accept headers for non-stream requests
