feat: Add inline keyboard support to auction listing inline queries

- Add interactive inline keyboard with bid, watch, and share buttons
- Implement separate inline query handler before dialogue system
- Fix dispatcher structure to handle both inline queries and regular messages
- Add dynamic bot username fetching for deep links
- Support rich formatted auction listing messages with pricing info
- Handle forward_listing:ID pattern for sharing specific auctions

Resolves inline query handling and adds interactive auction sharing
