### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: In cloud mode, paused Kafka routine load jobs could retain
their state and pause reason during FE replay while losing statistics,
progress, lag, and current partition metadata. Pause edit logs only carried the
state transition, so checkpoint replay could not reconstruct operator-visible
metadata that lived outside the FE transaction journal. This change persists a
metadata snapshot with Kafka pause operations, restores it during replay, and
retains the Kafka fields in subsequent checkpoint images. Legacy pause
operations without a snapshot keep the existing replay behavior.
### Release note
Paused Kafka routine load jobs preserve their statistics, progress, lag, and
current partitions after FE replay.
