   ### 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.
