fix(flatpak): working Flatpak build with KDE 6.9 runtime

- PyQt6 + PyQt6-sip added as Flatpak dependencies (not in KDE runtime)
- Pillow/numpy switched to cp312 pre-built wheels (SDK 6.9 = Python 3.12)
- QT_PLUGIN_PATH set to /usr/lib/plugins for runtime Qt integration
- resources/ copied to site-packages for fonts, i18n, icons, sounds
- pyproject.toml: compatible license format + .sql/.proto in package-data
- Auto-register desktop entry on AppImage startup (silent, no dialog)
- Runtime upgraded from 6.7 (EOL) to 6.9
