fix(windows): tray double-click flicker + GPU use when minimized

Browse Source 
1. Tray double-click (reported by @cucadmuh's brother-in-law):
   Windows fires a Click event on *both* halves of a double-click, so
   our left-click handler toggled visibility twice — the window popped
   up and immediately vanished. Switch the Windows branch to the
   `TrayIconEvent::DoubleClick` variant (Windows-only in tray-icon);
   other platforms keep the Click-on-Up behaviour. Matches the standard
   Windows tray convention (Discord, Telegram, etc).

2. GPU use while minimized:
   WebView2 on Windows keeps compositing infinite CSS animations
   (mesh-aura-a/b, portrait-drift, eq-bounce, track-pulse, led-pulse …)
   even when the window is minimized — steady visible GPU load on
   systems that should be idle. App.tsx now toggles a
   `data-app-hidden="true"` attribute on <html> on `visibilitychange`,
   and a single CSS rule pauses every `animation` at once via
   `animation-play-state: paused !important`. Zero cost when visible,
   catches all current and future infinite animations without
   per-element listeners.
