feat(exports): remove synchronous exports older than `EXPORT_CLEANUP_GRACE_PERIOD` DEV-1372 (#6515)

### 📣 Summary
Automatically removes old synchronous exports to prevent outdated files
from being accessible and to keep storage usage under control.


### 📖 Description
Synchronous exports are now cleaned up automatically after they expire.
A new recurring background task `cleanup_synchronous_exports` deletes
export files and their corresponding records once they are older than
the value defined in `EXPORT_CLEANUP_GRACE_PERIOD` (configured in
Constance, default: 30 minutes).

To ensure system stability, the cleanup runs in small batches of 200
exports per execution and uses a distributed lock to prevent multiple
workers from deleting the same exports simultaneously. This keeps
storage usage under control and prevents outdated export files from
remaining accessible.
