OpenClean 1.2.0: prenos za Windows

Added
- Safety net for deletions: create Windows restore points before cleanup and back up files before deletion, so entire runs can be undone. Both features are individually toggleable.
- Restore view: undo backed-up runs from Cleanup, Duplicates, Leftovers, Privacy and Large files sections, or discard backups.
- Windows restore point management: view, delete individual points, remove all but the most recent, and open system rollback via rstrui.exe.
- Storage & RAM analysis: sunburst visualization; click segments to zoom into folders and find space-consuming items.
- Large files finder tab: locate and move large files to the Recycle Bin, with warnings when files exceed bin capacity.
- Context menu management: disable Windows right-click menu entries without deleting anything.
- Delayed startup: stagger startup programs after sign-in instead of launching them all at once.
- License page: activation status, device release info and Pro feature overview.

Changed
- Recycle Bin moves now batch up to 128 paths per shell call, greatly improving performance for cleanups with many temporary files.
- Scheduled cleaning and batch uninstall moved to the Premium module; the core stays free and open source.

Fixed
- Restore point timestamps corrected (previously shifted by UTC offset).
- Large files deleted from the finder now correctly appear in the Restore view.

Security
- Self-check on startup: verifies the executable signature and locks modifying functions if the file was altered.
- Restricted DLL search path limited to System32 to prevent loading unauthorized libraries.
