chore(deps): update all dependencies to latest versions

- Used `pur` to bump dependencies in `requirements.txt` and `requirements-dev.txt` to their latest valid versions on PyPI.
- Ran `pre-commit autoupdate` to bump versions in `.pre-commit-config.yaml`.
- Verified that all unit tests pass with `pytest`.
- Verified that the main application still correctly starts up.
