fix extension import: use bulkCreate and handle uploadId param

Backend fixes:
- Use SourceAccountRepository.bulkCreate() instead of non-existent upsertSourceAccount()
- Change redirectUrl from /results?uploadId= to /?uploadId=
- More efficient bulk insert instead of loop

Frontend fixes:
- Add useEffect to load results when uploadId param present
- Calls loadUploadResults(uploadId) automatically on page load
- Cleans up URL param after loading

Resolves:
- "sourceAccountRepo.upsertSourceAccount is not a function" error
- "No routes matched location /results?uploadId=..." routing error
