### What problem does this PR solve?
Issue Number: None
Related PR: #62861
Problem Summary: Light schema changes create a finished compatibility job
after directly updating table metadata. Their column and inverted-index journal
records did not persist the job's creation and finish times, so replay rebuilt
the job with the replay timestamp. This changed SHOW ALTER history and delayed
expiration after every restart. Persist both timestamps at the metadata journal
commit point and restore them during replay. Register the live compatibility
job immediately after that commit so later inverted-index cleanup failures
remain consistent with replay, while treating missing fields from older
journals as replay-time defaults.
### Release note
Preserve light schema change job creation and finish timestamps across FE
replay.
