Automated Test Workflows and Dependabot

Re: https://github.com/bcgov/von-network/pull/275

I notice we're missing automated tests in this repo. Maybe there's a reason for that, but maintainability goes up 100 fold when tests can be run on command, and if Dependabot can automatically update dependencies.

Could we add some test workflows (and Dependabot workflow) to streamline updates and catch issues early? Happy to assist in setup if guidance on testable functions or scripts is provided.

Start by reviewing pull request 275 and the repository's existing scripts to identify testable functions and commands. Determine which automated test workflow and Dependabot configuration are needed, then verify that tests run automatically and dependency updates are configured.
