## Priority: Medium

## Description

The `apply_fallback_index/2` function is duplicated identically across 5 LiveViews, differing only in the stream key name:

- `lib/music_library_web/live/collection_live/index.ex:240`
- `lib/music_library_web/live/wishlist_live/index.ex:211`
- `lib/music_library_web/live/scrobble_rules_live/index.ex:188`
- `lib/music_library_web/live/record_set_live/index.ex:342`
- `lib/music_library_web/live/scrobbled_tracks_live/index.ex:255`

## Expected behavior

Extract to a shared helper, parameterizing the stream key name.
