Replace appreciate button with smart reaction button

- Remove appreciate button functionality (redundant with reactions)
- Create SmartReactionButton that shows:
  - Plus icon when no reactions exist
  - Top reaction + count when reactions exist
  - User's reaction + count when user has reacted
- Update ReactionPicker to show existing reactions first with counts
- Add visual indicators for selected reactions and counts
- Maintain full reaction functionality in single button
- Improve UX by consolidating reaction interactions
