### TL;DR
Improved the test stability for the turbo renderer by using reactive state observation instead of arbitrary timeouts. (https://github.com/toeverything/AFFiNE/actions/runs/14729729312/job/41340918866?pr=12071)
### What changed?
- Replaced `wait(FRAME)` and other timeout-based waits with reactive state observation using RxJS
- Added `filter` import from `rxjs/operators`
- Updated test assertions to properly wait for specific renderer states (`ready`, `pending`, `zooming`)
- Made tests more deterministic by waiting for specific state transitions rather than arbitrary time periods

## Summary by CodeRabbit
- **Tests**
- Improved test reliability by replacing fixed-duration waits with reactive waits based on renderer state changes, ensuring tests are synchronized with actual state transitions.
