feat(ui): theme skins — OG Codeman, Daylight Green, Daylight Blue

Add a per-device skin switcher in App Settings → Display:
- Three skins via html[data-skin]: og (original Codeman look),
  daylight-green, and daylight-blue (new default). Per-skin CSS-variable
  token blocks; the v1.0 "Carbon Aurora" component polish is scoped to
  non-og skins and parameterized so green/blue differ only by token values.
- Self-hosted Manrope (UI) + JetBrains Mono (terminal) variable fonts,
  served from /fonts (no external CDN, CSP-safe via font-src 'self').
- Per-skin xterm terminal theme with live re-theming of open terminals on
  skin change; skin-aware --term-bg so the terminal background fills cleanly
  (fixes the variable-height gap above the toolbar).
- Pre-paint inline script applies the saved skin before first paint (no
  flash); persisted per-device in localStorage + the settings blob, and
  kept out of the server settings payload (device-local).
