v3.7.3 - DAT self-heal fires automatically on startup

🐛 Bug Fixes

• Stale DATs now repair themselves on server restart. v3.7.2 taught DATSyncService to skip its already_synced fast-path whenever any DAT had file_count=0, but the self-heal only ran when sync() was explicitly called — via the UI sync button or POST /api/dat/sync. Users who had never clicked sync stayed stuck with 67 empty DATs (the classic pre-#49 state: every CD/softlist <disk> DAT showing 0 entries while Nintendo GameCube + Wii — the two <rom>-based ones — were healthy). Startup auto-sync previously gated on MAMEREDUMP_AUTO_SYNC=true AND an empty DAT store, so it never fired for someone who already had 69 DATs sitting in broken state.

  Startup now has a second trigger: whenever any DAT has file_count=0, a background sync kicks off unconditionally (no env-var gate, no empty-store gate). The service's existing self-heal logic then rebuilds the DAT set in place using the current parser. Fresh-install behaviour (MAMEREDUMP_AUTO_SYNC=true + empty store) is unchanged.

🧪 Tests

• test_has_stale_dats_empty_store_returns_false / _all_healthy_returns_false / _detects_zero_count — unit tests for the new DATStore.has_stale_dats() existence check.

📁 Files Changed

• app/services/dat_store.py — new has_stale_dats() method (single-row SQL existence check, cheap enough for startup).
• app/main.py — startup auto-sync split into two independent triggers; shared task-spawn helper extracted.
• tests/test_db_store_operations.py — three new tests for has_stale_dats().

⚠️ Upgrade Notes

• No action required. Restart the server once and stale DATs heal within ~60 s (given network access to the MAMERedump repo). If GitHub is unreachable the sync errors into the log and state is preserved — identical to the existing manual-sync behaviour.
