Catppuccin Latte and Mocha fallback palettes when theme files are unavailable,
replacing the legacy background and red values. Add a test covering the
no-theme-file path with independently defined expected palette values rather
than deriving them from cmuxDefaultLightThemeName or cmuxDefaultDarkThemeName.

Fixes #12204. Inactive terminals now keep full contrast by default, while explicit Ghostty dimming settings continue to work. Fresh-install adaptive colors use Catppuccin Latte/Mocha, including the fallback when theme files are unavailable. Terminal surfaces stay clipped to their panes during resizing and portal rebinding, with terminal dimensions derived from the actual scroll viewport.
This includes follow-up #12295, an authoritative-snapshot correction to the existing wheel-scroll test fixture, and independently specified fallback palette coverage. The fallback regression was committed before its fix and failed for both light and dark on the pre-fix commit.
Validation:
24125c7e4a.Production requires the normal macOS app release. No backend deployment, database migration, secret, or remote feature-flag change is needed. Managed defaults apply only when adaptive defaults are enabled and the user's effective Ghostty configuration has no directives. Explicit opacity remains authoritative; a fill-only setting retains Ghostty's normal dimming behavior.
