Use standard system package for ECDSA verification and add tests

[BjrInt]

Olivier writing a note on this PR I took over:
I have updated the branch with main, fixed the lint errors, added the dependency in the installation for the packages, and added a whole lot of tests for the auth decorator.

For testing I have by hand used the vm-operator-control-frontend tool that Hugo shared with me. I have also written unit test based on reverse engineering the code and the aforementioned tool queries.

It's ready for review and merge.

Use the standard jwcrypto package (apt install python3-jwcrypto) instead of the jwskate wrapper for ECDSA verification (used inside the trusted owner control code).

closes #384

To do before merging ⚠️

• The jwcrypto dependency must be installed (specified in a setup file)
• This is not end-2-end tested yet!

Mypy is unhappy about it, to fix.

For me it's ready for review

Thanks !

Can you add docstrings that explain the goal of each test ? I know it is usually in the name of the test function, but that is not always obvious.

What about adding type annotations on the code ?

I also had ruff reporting the following messages that seemed useful:

tests/supervisor/test_authentication.py:52:11: N801 Class name `mydatetime` should use CapWords convention 
tests/supervisor/test_authentication.py:53:21: DTZ001 The use of `datetime.datetime()` without `tzinfo` argument is not allowed
tests/supervisor/test_authentication.py:170:5: T201 `print` found
