fix: add Daily Reports to sidebar via get_app_list override

- Create openclaw_daily app (no models, just app config)
- Override get_app_list() in OpenClawAdminSite to inject Daily Reports item
- Use get_app_list approach (not nav-sidebar template override)
- Inject at top of app list for visibility
