Subject: [PATCH] Improve transaction fee handling in BlockAssembler

- Added logging for transactions that do not meet the minimum fee requirement, providing better visibility into fee-related decisions.
- Enhanced the handling of modified transactions by erasing them from the modified transaction map and inserting them into a failed transaction set when the fee is insufficient.

These changes aim to improve debugging and transaction management within the mining process.
