fix(table): validate snapshot timestamp drift

[GayathriSrividya]

Rationale

Align snapshot timestamp validation with the Java and Rust implementations by rejecting timestamps that drift backwards by more than one minute. Small clock skew remains allowed.

This also validates parsed table metadata:

• snapshot-log entries remain sorted within the one-minute tolerance
• last-updated-ms is not more than one minute behind the latest snapshot-log entry

Attribution

This revives the implementation from #3062 by @mrutunjay-kinagi. I cherry-picked the original authored commits onto the latest main, preserving authorship, and am reopening it because the earlier PR was closed automatically after inactivity. It includes the metadata-level validation added in response to @Fokko's review.

Verification

• make lint
• make test (3713 passed, 1534 deselected)
