- Add is_missing column to AssetCacheState for soft-delete
- Replace hard-delete pruning with mark_cache_states_missing_outside_prefixes
- Auto-restore missing cache states when files are re-scanned
- Filter out missing cache states from queries by default
- Rename functions for clarity:
- mark_cache_states_missing_outside_prefixes (was delete_cache_states_outside_prefixes)
- get_unreferenced_unhashed_asset_ids (was get_orphaned_seed_asset_ids)
- mark_assets_missing_outside_prefixes (was prune_orphaned_assets)
- mark_missing_outside_prefixes_safely (was prune_orphans_safely)
- Add restore_cache_states_by_paths for explicit restoration
- Add cleanup_unreferenced_assets for explicit hard-delete when needed
- Update API endpoint /api/assets/prune to use new soft-delete behavior
This preserves user metadata (tags, etc.) when base directories change,
allowing assets to be restored when the original paths become available again.

Architecture changes:
- API Routes -> manager.py (thin adapter) -> services/ (business logic) -> queries/ (atomic DB ops)
- Services own session lifecycle via create_session()
- Queries accept Session as parameter, do single-table atomic operations
New app/assets/services/ layer:
- __init__.py - exports all service functions
- ingest.py - ingest_file_from_path(), register_existing_asset()
- asset_management.py - get_asset_detail(), update_asset_metadata(), delete_asset_reference(), set_asset_preview()
- tagging.py - apply_tags(), remove_tags(), list_tags()
Removed from queries/asset_info.py:
- ingest_fs_asset (moved to services/ingest.py as ingest_file_from_path)
- update_asset_info_full (moved to services/asset_management.py as update_asset_metadata)
- create_asset_info_for_existing_asset (moved to services/ingest.py as register_existing_asset)
Updated manager.py:
- Now a thin adapter that transforms API schemas to/from service calls
- Delegates all business logic to services layer
- No longer imports sqlalchemy.orm.Session or models directly
Test updates:
- Fixed test_cache_state.py import of pick_best_live_path (moved to helpers.py)
- Added comprehensive service layer tests (41 new tests)
- All 112 query + service tests pass
