Add fit_aimpoint notebook for 2025-03

[taldcroft]

Description

This adds a new analysis notebook fit_aimpoint_drift-2025-03.ipynb which updates the aimpoint drift model by adding two jumps, one in 2023:046 (Safe Mode) and a second on 2024:001 (ad hoc).

Unrelated fixes

Modernized the ruff config and made some benign changes.
Also remove pyrightconfig.json, which is only causing problems.

Question on the notebook - I'm a little confused about why we have a drift model (the drift model code / the class definition) in the notebook and one in chandra_aca - should they share the same model (code)? If the calibration version in the notebook needs to be separate, some comment on that would be helpful.

I added this to the AcaDriftModel docstring in the notebook:

    Implementation note:
    - The class in this notebook is designed to work as a sherpa fit model. A key part
      of that is (1) initialization that processes a bunch of auxilliary data and (2) a
      ``__call__`` method that sherpa calls with the model parameters.
    - The `chandra_models.drift` model is designed to be initialized once with the drift
      model and then evaluated with the ``calc`` method. Even though the basic model
      computation is equivalent, it is not easy to re-use this class for the sherpa
      fitting process.
