Fix AppImage plugin loading, save timestamps, and INI corruption

- Add AppConfig::pluginsPath()/dllsPath() that respect MO2_PLUGINS_DIR
  and MO2_DLLS_DIR env vars, fixing plugin discovery when plugins live
  inside read-only AppImage squashfs (#22, game plugin not found errors)
- Preserve file modification times in save deploy/sync so games display
  correct save timestamps instead of all showing the same time (#17)
- Replace QSettings INI reader in saves tab with direct line-by-line
  parser to avoid backslash-as-line-continuation corruption of
  sLocalSavePath=__MO_Saves\ (#22, saves tab showing wrong directory)
- Add diagnostic logging to plugin symlink creation, save backup/restore
  operations to help diagnose silent failures through prefix symlinks
- Fix Python SONAME mismatch in AppImage build (patch portable Python
  SONAME to match librunner.so DT_NEEDED, preventing dual libpython load)
- Bundle PyQt6 Qt dependencies, improve RPATH for lib/ and plugins/
