fix(brand): recolor logo — terracotta accent, no blue (theme-aligned)

Brand assets из !100 пришли с DeepBlue/SkyBlue colors (design system
prototype). Ordinis app theme uses warm terracotta accent (#d97757 light /
#b05a2e dark) на cream/ink palette. Never blue. Recolored все 5 SVG +
inline Sidebar mark:

- favicon.svg: stroke #d97757, dots/core #b05a2e
- ordinis-mark.svg: orbits #e6e1d4 (line), dots accent gradient terracotta
- ordinis-appicon.svg: dark warm-ink tile (#2c2b27 → #1a1714), accent dots,
  white outer dots for contrast on dark
- ordinis-lockup-light.svg: terracotta orbits + warm-ink wordmark (Tektur)
- ordinis-lockup-dark.svg: warm-dark bg + terracotta accents + cream wordmark
- Sidebar inline svg: currentColor + text-accent, var(--color-line) для
  orbits — автоматически работает в both light + dark themes
- index.html: theme-color/mask-icon → #b05a2e (terracotta dark)

User feedback: 'DeepBlue никакого синего адаптируй под наши темы'.
