repo: backport mgr/dashboard fix for python-cryptography issues

Removes the (limited) runtime usages of python-jwt, and therefore,
python-cryptography from the mgr dashboard module.

This should restore dashboard functionality, if used alongside a
patched pyo3 for python-bcrypt.

+Subject: [PATCH 1/3] mgr/dashboard: Simplify authentication protocol By
+ removing the dependency to PyJWT we also remove the dependency to the
+ cryptographic library which in the dashboard module will create a crash. In
+ newer implementations of the library PyO3 is used to run rust code in order
+ to encrypt with Elliptic Curves. This is never used in the dashboard
+ communication so a much simpler implementation where we only use the hmac
+ sha256 algorithm to create the signed JWT message could be used.
