a single DELETE query and returns the reloaded empty set. Add Empty button
with confirmation prompt to both index and show view dropdowns.

## Implementation Plan
<!-- SECTION:PLAN:BEGIN -->
### 1. Add `empty_record_set/1` to `MusicLibrary.RecordSets`
Add a new public function that bulk-deletes all `RecordSetItem` rows for a given set in a single query, then reloads the set.

## Final Summary
<!-- SECTION:FINAL_SUMMARY:BEGIN -->
Added `RecordSets.empty_record_set/1` context function that bulk-deletes all `RecordSetItem` rows via a single `DELETE FROM record_set_items WHERE record_set_id = ?` query and returns the reloaded (empty) set. Added "Empty" dropdown button with confirmation prompt to both index and show LiveViews. Index view updates the card in place; show view shows a "Set emptied" toast. All 983 tests pass.
