chore: clean up codebase for production readiness

- Remove all console.log/debug statements from production code
- Add NODE_ENV checks for development-only logging
- Remove test scripts (test-feedback, test-image-security, test-backup-*, test-restore)
- Remove one-time fix scripts (fix-temp-photos, fix-migration-state, mark-migration-applied)
- Remove sensitive files (.env.backup, ADMIN_CREDENTIALS.txt)
- Update package.json to remove references to deleted scripts
- Replace console statements with logger utility in backend
- Secure error boundaries to not expose stack traces in production

This makes the codebase production-ready with no debug output or test scripts.
