Fix Stage 4 issues based on Hermes feedback

- Add currency field (AIT) to all pricing parameters (market_gpu_register, market_bid, market_sell)
- Fix market_bid to reference gpu_id instead of listing_id (GPU-specific)
- Fix market_buy to reference gpu_id instead of listing_id for consistency
- Add market_my-listings operation to check seller's own listings
- Add economics_model operation for price prediction (model_type, features)
- Add wallet_balance check at beginning of marketplace operations
