Investigate and possibly fix "imported but unused" Ruff lint from all __init__.py files
Ruff is complaining about "imported but unused" in our init.py files. But those imports have been around since the dawn of time (i.e. when Sun was still a thing). And if we make Ruff happy, we get errors like this when launching Orca:
Traceback (most recent call last):
File "/usr/lib/python3.11/site-packages/orca/script_manager.py", line 159, in _newNamedScript
script = module.Script(app)
^^^^^^^^^^^^^
AttributeError: module 'orca.scripts.apps.Thunderbird' has no attribute 'Script'
We should find out how to modify the script manager to solve this error.
