fix: update vite to resolve high-severity npm audit vulnerabilities

- Add AuditMiddleware that logs POST/PUT/PATCH/DELETE and GET /auth/me
- Logs structured JSON: event, timestamp, user_id, method, path, client_ip, status_code, duration_ms
- Excludes health endpoints and OPTIONS requests
- Never logs request/response bodies or auth headers/cookies
- Wire user_id from auth dependency via request.state
- Add add_audit_middleware() to app factory
