[CONTRIBUTION] Add Bitget Wallet Aggregaotr to dex_aggregator.trades

[kunwh]

Bitget Wallet Aggregator combines powerful algorithms and deep liquidity aggregation to deliver better prices and a seamless trading experience. With more and more transactions made through Bitget Wallet Aggregator, we would like to see it been covered in dex_aggregator.trades by Spellbook.

Plan:

1. Create intermediate table bgw_dex_aggregator_trades
2. Add sources into dex_aggregator.trades

This will enable community to analyze the data for DEX Aggregators and build dashboards/queries for Bitget Wallet Aggregator.
