feat(audit-logging): Implement Edge-compatible audit logging utility and safe logging module

- Added `auditLogEdge.js` for Edge Runtime compatible audit logging, including console logging and API fallback.
- Introduced `auditLogSafe.js` for safe audit logging without direct database imports, ensuring compatibility across runtimes.
- Enhanced `auth.js` to integrate safe audit logging for login actions, including success and failure cases.
- Created middleware `auditLog.js` to facilitate audit logging for API routes with predefined configurations.
- Updated `middleware.js` to allow API route access without authentication checks.
- Added tests for audit logging functionality and Edge compatibility in `test-audit-logging.mjs` and `test-edge-compatibility.mjs`.
- Implemented safe audit logging tests in `test-safe-audit-logging.mjs` to verify functionality across environments.
