fix(cms): implement v2 security and stability review findings

Resolves:
- CSRF false positive checked (global POST protection)
- Publish mutex to prevent git lock / double deploy
- Basic Auth rate limit checked before credential evaluation
- Memory leak in rate limiter (added GC interval)
- XSS in Toast messages
- XSS in data-path attribute
- CI healthcheck port mismatch (3000 -> 8080)
- Added security headers (X-Frame-Options, X-Content-Type-Options)
