Fix: Add routes and admin navigation

- Created appinfo/routes.php to register all routes
  - Admin routes: index, save, load, getStatus
  - API v1 routes: reports, getReport, generate, getStatus
  - Report routes: index, generate
- Added index() method to AdminController
  - Renders admin template via TemplateResponse
- Updated info.xml and appinfo/info.xml
  - Fixed navigation entry to point to route: analyticshub.admin.index
  - Added settings and navigation sections
- App now appears in Settings → Administration after enable/disable

Fixes issue where app didn't show up in Nextcloud toolbar after being enabled.
