Lift the 120s cap on Disney+ relative-seek so large seeks reach target

Browse Source 
Disney+ has no absolute seek on its blob <video>, so absolute seeks are
translated into repeated clicks of the player's relative skip button. The
click count was capped at 12 (=120s at 10s/step), so any seek further than
two minutes away silently landed short — breaking absolute-position sync
(e.g. syncing to 5:00 from far away never arrived).

Derive the step size from the matched button's own label (10s default,
some UIs use 5/15/30) and issue enough clicks to cover the full delta,
bounded at a sane maximum.
