Fixes the issue where cursor.getEstimatedSizeSinceMarkDeletePosition() would not subtract the size of individually acknowledged messages. Problem: - When messages are acknowledged out of order using asyncDelete(), the backlog count correctly decreases - But the backlog size remains inflated because individualDeletedMessages are not accounted for Example: - 5 messages (500 bytes total) - Individual ack of 3 messages - Before fix: backlog size = 500 (incorrect) - After fix: backlog size = 200 (correct) Fix: - Update ManagedCursorImpl.getEstimatedSizeSinceMarkDeletePosition() to calculate and subtract size of individual deleted entries - Uses average entry size to estimate deleted size - Thread-safe with proper locking Unit test: - testEstimatedSizeWithIndividualAcks() verifies the fix ### Does this pull request potentially affect one of the following parts: <!-- DO NOT REMOVE THIS SECTION.
