feat: add /admin command to list room admins

Implement /admin command as specified in issue #50:
- Lists all admin user IDs for the current room
- Output format: 'Room Admins:\n- @user1\n- @user2'
- Shows 'No admins configured for this room.' if none exist
- Available to everyone (no permission check needed)

Changes:
- Add cmd_admin function to commands.py
- Register CommandHandler('admin', cmd_admin) in bot.py
- Add /admin to command menu in post_init
- Update /help to include /admin command

Closes #50
