Clean up API documentation files by removing Phase X references:
Remove 'API Explorer will be inserted here in Phase X' placeholders from:
- 70+ API endpoint documentation files
- Authentication endpoints (login, logout, register, refresh)
- User endpoints (profile, settings, password)
- Device endpoints (registration, sync, shelves)
- Library endpoints (CRUD, folders, visibility)
- Media endpoints (items, progress, highlights, notes)
- Admin endpoints (users, analytics)
- Sync endpoints (Kobo, KOReader)
- OPDS endpoints
- Scanner endpoints
- Queue endpoints
These placeholders were from planning documents and have no meaning
to API consumers. The documentation is now clean and ready for use.
- Rename ScanEbooks method to ScanLibrary to reflect generic media scanning
- Rename ScanEbooksRequest to ScanLibraryRequest
- Update route handlers in scanner.go and library.go
- Rename scan_ebooks.md to scan_library.md
- No breaking changes: API endpoint remains POST /api/scanner/scan
