fix: rename main-menu Pause to "Pause Switchify" (#2228)

The bare "Pause" label on the main menu was ambiguous, especially
next to Media → "Play/Pause" which controls media transport. The
new label matches the language already used in the item's own
subtitle, in the Switch Action configuration screen, and in the
in-app HUD shown while paused — all of which already say
"Switchify".

Single string change in strings.xml; no code touched because
MenuItemRegistry references the value through R.string.menu_item_pause.
