Add unit tests to cover lucia (authentication - login/registration/tokens/access controls/etc)

[totto2727]

Currently, most tests fail and cause a lot of type problems.
Could this be the cause of the broken tests?
If this is the cause of my environment, I would be glad to know what settings I need to set up to get the tests to pass.

I am still trying to figure out this project.
So, I was planning to make tentative (comment out or any type) responses to the problem areas and submit a PR with the tests and type checks passing.

I also found in our research that there is a problem with the D1-related tests.
Is it possible to implement the tests in the current project structure?
If possible, we would like to address this issue gradually.
