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.

Suggested change

	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.
