Subject: [PATCH 1/3] VIZ: route evoked.plot() through MNELineFigure for
 default path

When evoked.plot() creates its own figure (axes=None), now routes through
_line_figure() to instantiate MNELineFigure instead of a plain matplotlib
figure. This aligns with the 2D plotting figure-class refactor direction
discussed in #7751.

Behavior unchanged for custom axes. Both plot_white() and plot_joint()
remain out of scope here.

Adds regression test to assert MNELineFigure instantiation for default path.
Closes #13747
