Close Badger DB after migration to prevent resource leak

[maradini77]

Description:

• Summary: Ensure Badger DB is closed in the migration path of DBStorageService to avoid file descriptor leaks and stale locks.
• What changed: Added ret.db.Close() on both success and error paths when target != nil in daprovider/das/db_storage_service.go.
• Rationale: Previously, the DB was opened but not closed during migration, causing a real resource leak.

Thanks for reminding me that we had deprecated the AnyTrust DBStorageService code over a year ago. I made a different PR to remove it #3701
