Fix Wine prefix deployment, INI handling, and data directory paths

- Fix data directory path to use ~/.var/app/com.fluorine.manager consistently
  (was ~/.local/share/fluorine in committed code)
- Fix VFS helper path in fuseconnector.cpp to use fluorineDataDir()
- Fix localAppFolder() to resolve Wine prefix AppData/Local on Linux
  instead of returning XDG ~/.local/share
- Add localAppName() virtual method for correct AppData folder mapping
  (Enderal→"enderal", Nehrim→"Oblivion")
- Fix mergeTweak() to use direct INI parser instead of QSettings which
  corrupts backslashes and URL-encodes spaces in keys
- Make resolveWineDataDirName() more robust with existence checks and
  fallback chain (documentsDirectory → gameShortName → gameName)
- Add comprehensive debug logging throughout Wine prefix deployment
- Fix INI case handling: copy instead of symlink for case-mismatched INIs,
  ensure both proper-case and lowercase aliases exist
- Remove native build script (Flatpak only)
