Refactor SpotBot and ExchangeService for balance retrieval

- Updated SpotBot to fetch token balance directly using the new GetBalance method in IExchangeService.
- Modified IExchangeService to include a method for retrieving balance by ticker.
- Enhanced ExchangeService to implement the new balance retrieval logic for both EVM and non-EVM exchanges.
- Updated TokenService to streamline contract address and decimal retrieval for various tokens.
- Adjusted TradesModal to reflect changes in position status handling.
