FIX: Set calibration plot axes to screen resolution if available

[flying-spagetti]

Reference issue:
Addresses #13538

What does this implement/fix?
As discussed in issue #13538, the calibration plot previously defaulted to tight axis limits around the available data points. This could make it difficult to interpret the calibration quality relative to the actual screen dimensions.

This PR updates the Calibration.plot method in mne/preprocessing/eyetracking/calibration.py. It adds a check for the screen_resolution metadata. If available, it uses these dimensions to set the xlim and ylim of the plot, placing the calibration points in their correct spatial context relative to the full screen.

Additional information
I reproduced this locally using the standard eyelink dataset. I manually injected a (1920, 1080) resolution into the object to verify the fix works as intended.

Thanks @flying-spagetti ! Checkout our contributing guide, You will need to add a change log entry, and looks like you also need to create an account on CircleCI. If you sign in to CircleCi with your GitHub account, then the CI's in this PR will be able to easily verify that there is a CircleCI account associated with your GitHub account, and the checks should run.

	Fix axis limits in :func:`mne.preprocessing.eyetracking.calibration.Calibration.plot` to use screen resolution if available, by :newcontrib:`Gnaneswar Lopinti`.
	Fix axis limits in :meth:`mne.preprocessing.eyetracking.calibration.Calibration.plot` to use screen resolution if available, by :newcontrib:`Gnaneswar Lopinti`.

(technically it is a method of the class Calibration).

Upon your next commit, the CircleCI Jobs should run! As long as the Pre-commit bot doesn't intercept you with fixes like it did to your last commit.

Thanks @scott-huberty for pointing the reference mistake!!
Applied the fix and i hope the CI checks should be good to go now.

Awesome! Look like the failures we are getting now are real! The good news is that the failures appear to be unrelated to this PR.

We might need you to hang tight for a bit until we fix them.

xref the failing test in the build_docs CI

Per the hint in the Warning admonition in the contributing guide, I think that the API entry point we need to reference is mne.preprocessing.eyetracking.Calibration, as this is the entry point we document in python_reference.rst, e.g. here

Thanks @flying-spagetti ! I'd like to update the main eyetracking tutorial to reflect this update plotting functionality. Give this message a thumbs up 👍 if it is OK that I push a commit directly to this PR.

[scott-huberty]

Alright! Here is the updated tutorial.

Marking for merge when green.
