refactor: clean up unused code and duplicate handlers

- Removed duplicate admin callback handlers from main.py (moved to admin_panel.py)
- Removed unused methods from BotController (handle_admin_panel, handle_lottery_management, handle_conduct_lottery_admin, handle_conduct_lottery)
- Removed unused keyboard methods from ui.py (get_lottery_management_keyboard, get_lottery_keyboard, get_conduct_lottery_keyboard)
- Simplified IBotController interface to only essential methods
- Simplified IKeyboardBuilder interface to only used methods
- Fixed cmd_admin handler to directly show admin panel
- Bot now uses centralized admin handlers from admin_panel.py
