WAU Compliance: agent collector, backend endpoints, frontend badge + panel

- Agent: WAU registry config check (include/exclude URLs), pending updates count
- Backend: /wau/compliance per customer, /wau/compliance/summary all customers
- Frontend: compliance badge in customer list, compliance panel in WAU tab
- config.js: no longer gitignored (secrets-free, reads from env/window.__RMM_CONFIG__)
- vite.config.js: reads backend URL from .env instead of hardcoded value
- .env.example added for clean setup
