refactor: Unify channel and DM interface styling

- Change DM message input from input to textarea (rows=2) for consistency
- Increase DM form padding (p-2 → p-3) to match channel view
- Increase DM status bar padding (p-1 → p-2) with larger font
- Replace "Last refresh:" with "Updated:" in both views
- Update DM status to show connection states (Connected/Connecting/Disconnected) instead of "Ready"
- Add loadStatus() function to DM page for proper connection monitoring
- Unify message input area height and status bar appearance across both pages
