Update app icon to adaptive form using ventoid-icon.svg from desktop. Set background to #222720 (RGB equivalent of 222720ff). Updated adaptive icon XML files (API 26+), foreground vector drawable, and app icon references.

Reviewed final head 4ad42d817f5bce9f390658f8126f07ad9a68962e after maintainer fixes.

• Connect both manifest icon attributes to the version-qualified launcher resource so adaptive and monochrome icons are actually used.
• Reuse the supplied transparent artwork with safe padding, preserving both antennas, eye cutouts and USB ports. Keep the same geometry for Android 13 themed icons and the requested #222720 background.
• Composite the legacy icon over the background so its white USB body remains visible on light launchers.

Validation: release lint and debug APK build passed locally (zero lint errors); AAPT inspection confirms the manifest references, legacy/adaptive/Android 13 variants, and legacy background. Circle, rounded-square, squircle and themed artwork previews were visually checked; the artwork fits the 66dp safe circle. Final CI passed Android verification and workflow lint.

Thanks for contributing the adaptive icon update, @hexman1999! The new artwork and background are now merged. I added a few follow-up fixes for launcher wiring, icon padding, themed icons, and legacy Android contrast, and the final CI checks passed. Appreciate your contribution to Ventoid!
