Fixes Onboard CLI import errors

[Andrewyx]

Description

This PR gets robot diagnostics CLI working on the PIs robots again after migration in #3459.

The fix for the linked resolved issue do not inherently pertain to the changes in this PR. Instead, the fix for that seemed to be to rm -rf the /opt/tbotspython virtual environment and rerun setup_pi.yml. The reason for this is due to the accumulation of old python version within the venv over the years. This results in a python mismatch and the CPython crash.

Warning

ALL ROBOTS MUST UNDERGO THE CLEARING OF /opt/tbotspython TO WORK. Ideally, we should add this deletion to setup_pi.yml

Additionally, it seems some subtle changes were introduced since the Bazel 8 migration with resulted in the declaration of paths to become more strict. Hence, the changes in this PR reflect this and introduce module names to address this.

Testing Done

Works on robot. Status visible, commands can be issued, no errors produced.
Run-able with ./tbots_cli
