feat: implement database layer and rename auction -> listing

Major Changes:
- Set up SQLx database connection and migration system
- Create complete initial database schema with all tables
- Rename 'auction' to 'listing' throughout codebase for better terminology
- Update bot commands: /newauction -> /newlisting, /myauctions -> /mylistings
- Update all database tables: auctions -> listings, auction_medias -> listing_medias
- Update foreign key relationships and indexes
- Add automatic database migration on startup
- Update documentation and README
- Complete backlog tasks: task-001, task-002, task-010

The bot now has a solid database foundation ready for implementing core business logic.
All tests pass and code compiles successfully.

 ## Core Features
 
-### Auction Types
+### Listing Types
 1. **Standard Auctions**: Traditional time-based bidding with anti-sniping protection
 2. **Multi-slot Auctions**: Multiple winners (e.g., 3 commission slots available)
 3. **Fixed Price Sales**: Set price with limited quantity
 4. **Blind Auctions**: Bidders submit amounts with descriptions; seller chooses winner (not necessarily highest bid)
 
 ### Key Functionality
-- **Telegram Bot**: The bot is interacted with primarily through Telegram. Sellers can create auctions, and view bids on auctions. Buyers can bid on auctions and view their bids.
+- **Telegram Bot**: The bot is interacted with primarily through Telegram. Sellers can create listings, and view bids on listings. Buyers can bid on listings and view their bids.
 - **Proxy/Automatic Bidding**: Users set maximum bid; system auto-bids up to that amount
 - **Anti-sniping Protection**: Configurable time extension if bid placed in last N minutes
 - **Buy-now Option**: Instant purchase at fixed price
-- **Media Support**: Multiple images/videos per auction on the telegram post.
+- **Media Support**: Multiple images/videos per listing on the telegram post.
 - **Outbid Notifications**: Configurable user notifications
 - **Non-payment Handling**: Track failed payments, allow selection of next highest bidder
 - **Localization Support**: Multi-language structure (to be implemented)
