Review Comment:
Each part event is now handled in O(1) and no RocksDB scans on the hot path.
OmTableInsightTask wires MULTIPART_PARTS_TABLE events into this handler while
preserving the existing generic per-table object-count tracking
(multipartPartsTableCount) that already existed for this unregistered table.
Also updated testcases.
