fix: align mentor header right-side icons with other pages

Remove the stale body[data-active-view="mentorView"] .app-page-context
override from the mentor page stylesheet. It was added to widen the shell
title slot for the mentor subtitle, but the shared shell owner
(.main .app-header .app-page-context) already drives that slot with higher
specificity, so the page override was dead and only left a page-scoped rule
on a shared shell element. Deleting it lets mentor reuse the same canonical
shell header as every other page, keeping the right-side header actions
flush with the right edge.
