Update handling of commit timestamps

[loloxwg]

The commit timestamps handling has been revised to better track the max commit timestamps in GlobalCatalogDeltaEntry. Previously, any mismatch between commit timestamps would result in an error. Now, such discrepancies are handled by injecting the segment entries, which have commit timestamps greater than max_commit_ts, back into the global_catalog_delta_entry_ list.
