Enhance DataController and BotService with new configuration and bot name checks

- Added IConfiguration dependency to DataController for environment variable access.
- Updated GetPaginatedAgentSummariesCommand to include a flag for filtering profitable agents.
- Implemented HasUserBotWithNameAsync method in IBotService and BotService to check for existing bots by name.
- Modified StartBotCommandHandler and StartCopyTradingCommandHandler to prevent duplicate bot names during strategy creation.
