Visual indicators of events loaded

Visual indicators: Event kind badges now have colored borders:
    - Green border = Events loaded (with count shown)
    - Red border = Not loaded yet
  2. Hint text: Added explanations below the badges explaining what the colors mean
  3. Event counts: Shows the number of loaded events for each kind in parentheses
