Email, calendar, and files no longer appear in the nav or as usable pages
unless they are installed. The nav refreshes whenever a service is installed
or removed via the new pic-services-changed CustomEvent.
Changes:
- routes/services.py: add GET /api/services/active endpoint
- api.js: add servicesAPI.listActive()
- App.jsx: replace hardcoded coreServiceChildren with dynamic state fetched
from /api/services/active; SERVICE_META maps ids to nav entry shapes
- ServiceNotInstalledBanner.jsx: new component — admin gets catalog link,
peer gets "contact admin" message
- EmailPage/CalendarPage/FilesPage: show banner when service not installed
- ServicesIndex.jsx: remove CoreServiceCard + CORE_SERVICES "Built-in"
section; rename Remove → Uninstall; dispatch pic-services-changed on
install/uninstall success
- MyServices.jsx: conditionally render service cards based on active list;
placeholder card when absent; page-level notice when nothing is installed
- tests/test_services_active_endpoint.py: 4 new endpoint tests
