### Description of PR Since DNs do not report deleted blocks to NNs, in standby and observer namenodes, if not removed, `pendingDNMessages` will never drain messages from blocks that have already been deleted, leading to a leak. <img width="1426" height="672" alt="image" src="https://github.com/user-attachments/assets/51e871ec-e85a-45d0-ad1f-263c107b1a33"; /> The solution is to clean up the messages when the block is removed in `BlockManager#removeBlock()`. ### How was this patch tested?
