- Add deleted_at column to AssetReference model and migration
- soft_delete_reference_by_id sets deleted_at instead of removing rows
- DELETE /api/assets/{id} defaults to soft-delete; delete_content=true
for hard-delete
- Add deleted_at IS NULL filters to read queries, tag queries, and
scanner queries so soft-deleted refs are invisible
- restore_references_by_paths skips soft-deleted refs
- upsert_reference clears deleted_at on explicit re-ingest
- Add tests for soft-delete API behavior, scanner persistence, bulk
insert, enrichment exclusion, and seed asset garbage collection

Replace --disable-assets-autoscan with --enable-assets so the assets
system (API routes, database sync, background scanning) is off by
default and must be explicitly opted into. Expose the flag as an
"assets" entry in SERVER_FEATURE_FLAGS so the frontend can read it
from GET /features.
