Description

Jira Link: DB-2155 GetEarliestNeededLogIndex needs to return a list of (op_id, op_id_source) so we can show the reasons for keeping a particular op id in the UI.

Contributor guide

Research direction
Find all callers of GetEarliestNeededLogIndex, then modify the function to return a list of (op id, op id source) pairs and update all callers to use the new return value, ensuring UI can display the reasons for keeping op ids.
