Evolu tests now do not depend on hardocded values but compute the expected value from the `delegated_idenetity_key` of the tested device. Therefore enabling testing on HW devices where the master key is not initialized to all zeroes.
A check function was added to the `sign_registration` tests to determine if the device has Optiga available. If not, the test will mark itself as `xfail` - we expect Optiga signing to fail if there is no Optiga.
All the Evolu test have been simplified so that the logic is the same for THP and non-THP devices.
Lastly, the verification of certificate chain and Optiga and Tropic signatures and certificates has been refactored from `test_authenticate_device.py` as it is now used in other tests.
