* Initial plan
* perf: optimize gacha import with batch transactions and reduced UI delays
- Wrap DB inserts in transactions (batches of 500) for mergeUIGF/mergeUIGF4
- Pre-transform all data before batch insert loop
- Pass timeout: 0 to showLoading.update in progress callbacks
- Remove 1500ms snackbar delay in cleanGachaRecords
- Reduce per-item loading update delay in refreshGachaPool
