[Command] Test Command Authentication works on FLIGHT mode builds (post bazel migration)

[devYaoYH]

Enable HMAC authentication with the following build flags:

bazel build :samwise --config=pico-hat --copt='"-DPACKET_HMAC_PSK=..."'

Note

The above build assumes one is testing with the pico-based radio chip (instead of picubed)

And copy over the hmac passkey from the ground_station/config.py file. Also run the test with a different passkey in the ground station config.py file to verify that commands are no longer accepted by the satellite.
