Organize project structure and add APK build tools

Changes:
- Organized build tools into build-tools/ directory
- Added multiple APK generation methods:
  - Docker-based Bubblewrap builder
  - Python-based simple APK creator
  - Build instructions for various methods
- Cleaned up directory structure:
  - Moved KML backups to data-backups/
  - Created output/ directory for generated APKs
  - Updated .gitignore for cleaner repository
- All build scripts and tools ready for APK generation

Build options available:
1. Online: PWA2APK.com (recommended)
2. Docker: ./build-tools/build-apk-local.sh
3. Python: python3 build-tools/create-simple-apk.py

The app is now fully deployable as:
- PWA (installable from browser)
- APK (Android app)
- Docker container (server deployment)
