fix: restore original route paths and parameters

Revert unauthorized route changes made during router refactoring:

Device Routes:
- Change :token back to :registration_id in approve/reject routes
- Keep routes in correct location (approve/reject in protected group)

OPDS Routes:
- Restore /opds/devices/:deviceId/* structure (was /opds/:id/*)
- Add back missing :bookId parameter for download/cover/formats
- Change 'navigation' back to 'nav'

Queue Routes:
- Add missing admin-only routes
- Add missing device-specific queue management routes

All routes now match original main.go signatures exactly.
Breaking changes reverted - API contract restored.
