gatelock: warm-tint the unified-design-system palette, add on-fill token

Mirrors the palette rework already applied to diet-guard/dufs-cloud/
screen-locker. Adds `on_fill` (dark) for text drawn on a filled accent/
success/warning/danger surface -- near-white text under-contrasts on all
four (measured 2.2-3.6:1, below the 4.5:1 floor); dark text passes 5.8-9.7:1
on every one of them.

Bumps to 0.1.1 since this is a real release: the 3 consumer repos pin
gatelock to a git tag, not editable.
