fix(vegas): a static pause redraws its plugin for the whole pause

Browse Source 
The pause called display(force_clear=True) once and slept out the
duration, so a plugin that rotates its screens or animates (Fantasy
Blitz's playlist) was frozen on its first frame. The pause now calls
display() again at the rotation's rate: once a second, or the high-FPS
interval for a plugin that declares needs_high_fps (or scrolls). Only
the first call clears. A redraw that finds update() holding the plugin
lock is skipped; the pause carries on. Interrupt checks and the
watchdog beat still run every 0.1 s; a raise still ends the pause.
