fix: security hardening - remove backdoors and disable TLS verification bypass

- Remove NO_AUTH environment variable bypass (production security risk)
- Fix InsecureSkipVerify: true -> false in FVM and HTTP client code
- Restore proper auth middleware on all protected routes
- All 31 modified files now have clean security posture
