fix(studio,producer): post-merge regressions and open issues (#1643)

- fix gsapDragCommit.test.ts import for commitGsapPositionFromDrag
- add generateId() helper with insecure-context fallback (fixes #1637)
- enable STUDIO_KEYFRAMES_ENABLED by default
- prevent clock duration from shrinking during playback (fixes #1636)
- add maxRetries to rmSync cleanup calls to handle ENOTEMPTY race (fixes #1644)
