feat(panel): one RESET on every tab, back to the app's defaults

RESET was look-relative: it only put the sliders back on the values the
active recipe ships with, so the look itself (a saved recipe, a film sim)
survived the tap. It now restores the state a clean start leaves — the
PROVIA startup look, every parameter neutral, frame off, the custom and
GPS watermarks back to their defaults — and it sits on every tab, pinned
outside the scrolling chip row so it can never scroll out of reach.

Mode and aspect ratio stay put: they frame the shot being worked on, not
the look.
