Refactor BotController and BotService for improved bot management

- Cleaned up constructor parameters in BotController for better readability.
- Enhanced StartCopyTradingCommand handling with improved formatting.
- Updated bot deletion logic in BotService to delete associated positions and trigger agent summary updates.
- Added new method in TradingService for deleting positions by initiator identifier.
- Implemented error handling in StopBotCommandHandler to ensure agent summary updates do not disrupt bot stop operations.
