feat: apply predicate on WatchTx [grpc]

[nicolasLuduena]

Enhancements to transaction filtering and matching:

• Added functions outputs_match_address, outputs_match_asset, matches_output, matches_cardano_pattern, matches_chain, and apply_predicate to facilitate detailed transaction pattern matching based on address and asset criteria.

Changes to gRPC service implementation:

• Updated roll_to_watch_response to pass the request parameter to block_to_txs for transaction filtering.
• Adjusted WatchTx method in WatchServiceImpl to handle the WatchTxRequest structure and pass it through the response generation pipeline.
