v1.3.1 hotfix: status-bar overlap + font fallback

- LedgaTopBar now applies WindowInsets.statusBars padding. Previously
  enableEdgeToEdge was on but the top bar drew at y=0, so the avatar
  and trailing icons sat under the system clock / WiFi indicator.
- PillTabBar uses WindowInsets.navigationBars padding instead of a
  hardcoded 21dp bottom so the floating pill sits above the system
  gesture pill on devices like the S24 Ultra.
- Typography switched from Google-Fonts Inter to FontFamily.SansSerif.
  Inter requires a downloadable-fonts round-trip via Google Play
  Services that doesn't always succeed; the fallback was hitting
  FontFamily.Default, which inherits the user's system font choice —
  on Samsung One UI that's frequently a handwritten / script style
  and broke the type rhythm everywhere. SansSerif uses the platform
  sans (One UI Sans on Galaxy, Roboto elsewhere) regardless of user
  preference.
