feat(pc): add app icons, installer branding, and update tray icon (#234)

* feat(pc): add app icons, installer branding, and update tray icon

Generate all missing icon assets from the brand logo SVG:
- icon.icns/ico/png for macOS and Windows app icons
- DMG background with branded gradient, title text, and drag arrow
- NSIS installer header and sidebar with brand gradient + logo
- Update system tray icon from old "M" letterform to logo silhouette
  (outer ring + center dot) matching the current brand identity

* fix(pc): regenerate 2x tray icon PNG with valid IDAT stream

The previous 2x PNG had a corrupted IDAT stream that prevented
decoding on HiDPI displays, causing fallback to the 1x icon.
Regenerated both 1x and 2x PNGs with verified integrity.
