Provide a small KAutoSaveFile-compatible implementation for the no-KF5 build path and use it to keep the existing crash-recovery code active when BUILD_WITH_KF5=OFF. The normal KF5 build still uses the KDE KAutoSaveFile implementation. Assisted-by: pi coding agent / Mika (OpenAI GPT-5.5)

It stores crash-recovery files below the application data autosave folder
