feat: implement auction bidding and resource adjustment commands

- Added `adjustGeneralResources` command to handle resource adjustments for generals.
- Introduced `patchGeneral` command for updating general attributes.
- Created `auctionBid` command to facilitate bidding in auctions with validation.
- Refactored database interactions to use transactions for auction bids and resource adjustments.
- Enhanced error handling for auction and resource operations.
- Updated command handling in the turn daemon to support new commands.
- Introduced `AuctionBidder` interface and implementation for managing auction bids.
- Improved overall structure and readability of auction-related code.
