fix(client/apple): the tray blur goes full-bleed by layout, and its frost sinks to black

Round-3 field findings: the pop-in had retreated to the X axis alone -
the one growth still left to safe-area resolution (the landscape side
insets), which settles a beat after insertion, outside any geometry
group and outside the view's own transaction. The scrim now reaches
full-bleed purely by layout: a fixed 80 pt negative-padding overhang on
the outer edge and both sides replaces ignoresSafeArea entirely, so
every axis is deterministic from the first frame (and orientation no
longer changes the gradient's proportions). The mask's strong region
moves to 0.65 to account for the overhang leading the gradient.

And the frost reads black now, not grey: an ink.shade(0.35) wash inside
the mask sinks the material's luminance lift toward the palette's shade
- black on a dark field, palette-honest on a pale one.
