Pull request overview

Updates the backend API and SQL queries to expose newly added Blockfrost OpenAPI fields (tx_slot, block_height, block_time, treasury_donation) on specific /accounts/{stake_address}/* and /txs/{hash} endpoints, aligning the implementation with the referenced OpenAPI change.

Changes:

• Bump @blockfrost/openapi to 0.1.86-beta.2 and update lock/Nix yarn artifacts accordingly.
• Add treasury_donation to /txs/{hash} SQL + route response and extend the Tx query type.
• Extend stake-address accounts SQL queries (paged + unpaged) to return tx_slot, block_height, block_time, and update related query types and unit fixtures.
