…kpoint restart (#61997) ### What problem does this PR solve? Problem Summary: 1. When FE restarts from a checkpoint image, `replayOnCommitted()` is not called for transactions committed before the checkpoint. Since `jobStatistic` in `StreamingInsertJob` lacked `@SerializedName`, it was not written into the image, causing `scannedRows` and `loadBytes` to reset to zero after every checkpoint-based restart. 2. add restart case for cdc tvf #### Root Cause `jobStatistic` accumulates statistics via `+=` in `replayOnCommitted()`. Unlike `offset` (which is an assignment and idempotent), accumulated values cannot be recovered from post-checkpoint txn replay alone. The field must be persisted in the image to survive checkpoint restarts.
