Features: 1) Add logging for transaction processing errors in payments/signals.py; 2) Add return type annotations for core tasks in core/tasks.py;

Fixes: 1) Avoid unused variable warning in `update_products_task` by removing exception variable `vie`; 2) Add missing imports for `logging` and `traceback` in `payments/signals.py`;

Extra: 1) Minor formatting fix in `dbbackup.py` to consolidate FTP URL string construction; 2) Remove unnecessary newline in `core/vendors/__init__.py`.
