Problem
The eraseTable and erasePartition methods in CatalogRecycleBin had an ABA race condition. They collected expired IDs under a read lock, then iterated over them under a write lock. However, between the read lock release and the write lock acquisition, entries could be re-added with the same ID (e.g., after a table/partition was restored and then dropped again), causing the write lock section to erase the wrong entry.
