fix(studio): selectedGsapAnimations empty after gesture recording (#1646)

- include target in useGsapAnimationsForElement fetch key so a selection
  change triggers a re-fetch even at the same cache version
- add gsapCacheVersion to useDomEditPreviewSync deps so the selection
  re-syncs after every soft reload
- trim manualEditsDom.ts to 600 LOC (filesize compliance)

Fixes #1645
