Phase 2: cut the APK over to the React app

webDir moves from www to dist, and npm run apk now builds with Vite
instead of copying the reference. The Phase 1 pipeline is still there as
apk:phase1, so the wrapper that has been installable throughout can be
rebuilt if the port turns out to have a problem on the device.

Verified without the phone: Vite builds, Capacitor copies dist, all three
plugins are still found, Gradle packages, and the APK now contains the
React bundle and the three self-hosted woff2 files with none of the old
Phase 1 assets left behind.

What cannot be checked from here is the part that matters most - a real
two-finger chord, haptics, the back button, and whether the drill boxes
already on the phone survive the switch.
