fix(ui/theme): replace light theme with clean material design palette
The previous light theme used warm/organic off-whites and muted tones
that felt muddy. Replaced with a crisp material-inspired palette:
Surfaces
- bg-void #f0f2f5 (cool-grey base)
- bg-base #f5f7fa (very light cool background)
- bg-raised #ffffff (pure white cards)
- bg-hover #e3e8f0 (clear interactive hover)
Typography
- text-primary #1a202c (near-black, high contrast)
- text-secondary #4a5568 (balanced mid-grey)
- text-muted #8896a7 (clear but soft)
Accents (Material Design colour values)
- cyan #0277bd Blue 700 (replaces washed-out #007fa8)
- green #388e3c Green 700
- amber #e65100 Deep Orange 900 (warmer, more material)
- red #d32f2f Red 700
Shadows
Dual-layer transparent shadows for better depth perception on light
backgrounds.
Also adds @keyframes fade-in-up used by the shortcuts add form.
