Add min and max balance filters to bot management

- Introduced optional parameters for minimum and maximum BotTradingBalance in BotController, DataController, and related services.
- Updated interfaces and repository methods to support filtering by BotTradingBalance.
- Enhanced TradingBotResponse and BotEntity models to include BotTradingBalance property.
- Adjusted database schema to accommodate new BotTradingBalance field.
- Ensured proper mapping and handling of BotTradingBalance in PostgreSQL repository and mappers.
