Fix Snackbar layout inflation crash by aligning app bootstrap theme with AppCompat

[Copilot]

Snackbar.make(...) was crashing at runtime while inflating design_layout_snackbar_include because the app bootstrap theme did not provide the AppCompat attribute set expected by Material/AppCompat snackbar internals. This surfaced as Failed to resolve attribute ... ThemeOverlay.AppCompat.Dark during TextView inflation.

• Theme baseline correction

  • Updated the app bootstrap theme parent to AppCompat DayNight so snackbar include/text appearance attributes resolve consistently.

• Crash path addressed

  • Prevents the UnsupportedOperationException raised from TypedArray.getColorStateList(...) in snackbar text appearance resolution under ThemeOverlay.AppCompat.Dark.
