feat(ui): m5 shard-website design pass

Restyle every Android screen with the shard-website theme from the
"Runic Gateway Screens" design (docs/android/PLAN.md §M5): deep blue-black
surfaces, a slate-blue accent, parchment serif body copy, and an engraved
Cinzel serif display face. The app is now dark-only, matching the design.

Theme layer (propagates to all token-based screens):
- Color.kt: replace the placeholder purple palette with named shard tokens.
- Theme.kt: one dark color scheme mapped onto the palette + 8/12/16dp shapes;
  drop the light branch; keep optional per-shard brand-accent seeding.
- Type.kt: full type scale — Cinzel display/headline/title, serif body,
  letter-spaced sans labels/buttons.
- Font.kt + res/font/cinzel_variable.ttf (SIL OFL, app/licenses/Cinzel-OFL.txt):
  the Cinzel display family, pinned to 500/600/700 via FontVariation.

Shared components (ui/components/ThemeComponents.kt): StatusPill (semantic
tones), OnlineDot, SectionLabel, FeatureCard (gradient), StatBar — adopted
across Home, Account, Shard hub, Champs, Characters, Houses, and the
character sheet (vitals/skills meters).

Shell: dark top-bar + drawer styling; dark launch theme and light system-bar
icons so the first frame matches (no white flash).

Build (assembleDebug) and unit tests green.
