[eth_sendRawTransaction Fast Return] Deprecate the original logic that waits for transactions to be fully processed before returning the transaction hash.

[quiet-node]

Problem

The EPIC - Fast Return on eth_sendRawTransaction has been successfully implemented. It introduces a feature flag allowing eth_sendRawTransaction to return the transaction hash immediately after passing prechecks, with all transaction processing logic shifted to the background asynchronously. This feature was enabled on the mainnet and is currently under monitoring. As the feature matures and stabilizes, the original logic—waiting for the transaction to be fully processed before returning the hash—can be deprecated and removed from the main workflow.

Solution

Deprecate and remove the original logic, making the fast return the default and sole option.
