- Wire preset state through QuickEntryBox and InlineCreateCard new-task flows
- Add regression tests for preset selection in ModelSelectionModal, QuickEntryBox, InlineCreateCard, and ListView
- Update dashboard README with preset-in-quick-add documentation
- Clean up unused footer-safe-layout test and adjust styles
