Highlight reaction counts when active user has reacted

Changes:
- Reaction counts now show in highlight color (text-highlight) when the
  active user has reacted with that emoji
- Added font-semibold to make user's reactions more prominent
- Checks if activeAccount.pubkey is in reaction.pubkeys array
- Provides clear visual feedback showing which reactions you've made

This makes it easy to see at a glance which reactions are yours in a
conversation with many reactions.
