fix(bulkProcessing): keep activity log progress in sync with bulk items DEV-2498 (#7337)

### 📣 Summary
This PR fixes bulk transcription and translation jobs reporting stale
progress on the project activity page.

### 📖 Description
#### Problem
The data table and the project activity page report bulk processing
progress from two different sources. The data table reads the bulk
action item rows directly, so it is always current. The activity page
reads a snapshot stored on the project history log, which is written
when the job starts and refreshed only as a side effect of a periodic
Celery task. That made the activity page only as fresh as the periodic
task.

#### Solution 
The history log is now refreshed as each submission reaches a terminal
state, rather than waiting for the next poll, so the activity page and
the data table move together. Because several submissions can finish at
once and refreshing the log is a read-modify-write of a single JSON
field, the refresh takes a row lock so concurrent updates cannot be
lost.
