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. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
