FIX: correct label orientation for 0-90 deg nodes in plot_connectivity_circle

[paavalipopov]

Reference issue (if any)

What does this implement/fix?

In mne.viz.circle._plot_connectivity_circle, the condition on line 341 if angle_deg >= 270 that determines labels horizontal alignment only covers the 270–360° range (3–6 o'clock). Nodes in the 0–90° range (12–3 o'clock) are incorrectly treated as left-half nodes, and their labels appear pointing inward, which looks like a bug.

Fix: extend the condition to angle_deg >= 270 or angle_deg < 90, matching the full right half of the circle.

looks good to me, only a minor change in the test docs and the location of the test function (just updated)

It looks like this branch includes several unrelated commits or working-tree changes. Could you reset/rebase the branch onto current main and recommit just the relevant files? Based on the commit history, three commits are unrelated to the current work

thanks @paavalipopov this is a nice PR. Thanks for the thorough test. I have a couple of suggestions to tidy it a bit, which I think should be uncontroversial so I'll apply them and mark for merge.
