Rewrite as Flutter app and rename to Quicklogmain

Drop the Go/Fyne implementation and replace it with a native Flutter app
targeting Android (primary) and Linux desktop (development). Rename
quicklogger -> quicklog throughout (project, applicationId, MethodChannel,
cache filename, AppBar title, Linux binary).

Storage on Android moves to /Android/data/org.buetow.quicklog/files/ so
MANAGE_EXTERNAL_STORAGE is no longer required. Share-intent receive is
preserved via a Kotlin ShareActivity that writes shared text to the app
cache, which Dart reads through a MethodChannel on app resume; MainActivity
also accepts SEND directly so launchers that prefer the main target work.

New since the Fyne version: an entry browser screen with read-only viewer
and long-press delete.

Cross-compiling to Android ARM from amd64 Linux no longer needs Docker /
fyne-cross / NDK -- flutter build apk emits ARM binaries directly.
