Make Feed menu item selected when no filters active and clear filters on click

- Created useFeedFilters hook to detect active filters and clear all filters
- Feed menu item now shows as selected when no filters are active
- Clicking Feed clears all active filters (object type and tag filters)
- Disabled transitions on menu items to prevent glow/blinking effects
- Added !important to all focus/hover/active states for consistent behavior
