feat(winui3): colored ISO pills + active-speaker accent on rows
Some checks failed
CI / build-and-test (push) Has been cancelled
Details

Browse source 
Two visual upgrades on the participant rows:

  * The ISO state pill now flips background / border / text colors
    based on the engine's reported state — green for LIVE, coral for
    ERROR, amber for STARTING / NO SIGNAL, neutral surface for OFF.
    Brushes pulled from the ThemeResource ramp (StatusLiveBg /
    StatusLive / AccentCoralBg / AccentCoral / StatusWarnBg /
    StatusWarn / BgSurface / BorderStrong). Mirrors the WPF host's
    IsoToggle data-trigger behavior but built imperatively.
  * The active-speaker left accent — a 3px cyan border at the row's
    left edge — appears when MainViewModel's 1Hz stats tick marks the
    loudest participant. Hidden by default; flips Visibility on
    PropertyChanged(IsActiveSpeaker).

Row layout extended to accommodate: column 0 = 3px accent strip,
column 1 = 20px spacer, column 2 = name + codec (1*), column 3 =
output name (140px fixed), column 4 = ISO pill (auto).

ApplyIsoPillStyling is the brush-mapping helper — called once at row
construct and again on every IsoStateLabel / IsEnabled change. The
brush keys all resolve via Application.Current.Resources rather than
ThemeResource markup since the row is constructed imperatively (no
XAML to apply ThemeResource markup against).

Verified end-to-end: dotnet build clean, app launches with 3 live
participants in the row, all pills showing OFF (neutral surface +
strong border). Once a participant goes through OFF → STARTING (amber)
→ LIVE (green), the pill colors will update on the 1Hz stats tick.
