fix: improve QuickAddTask and TagInput components

- Added `min-w-0` class to the title input in `QuickAddTask` for better layout handling.
- Updated priority select to use `flex-shrink-0` and `w-10` for consistent sizing and added title tooltip for better UX.
- Enhanced `TagInput` to support `compactSuggestions` prop, adjusting suggestion display based on available space.
- Modified suggestion container to conditionally apply grid classes based on `compactSuggestions`, improving responsiveness.
