feat: streamline S3 restore with single-step flow and improved UI consistency

Major architectural improvements:
- Merged download and restore into single atomic operation
- Eliminated separate S3DownloadFinished event (redundant)
- Files now transfer directly: S3 → helper container → server → database container
- Removed download progress tracking in favor of unified restore progress

UI/UX improvements:
- Unified restore method selection with visual cards
- Consistent "File Information" display between local and S3 restore
- Single slide-over for all restore operations (removed separate S3 download monitor)
- Better visual feedback with loading states

Security enhancements:
- Added isSafeTmpPath() helper for path traversal protection
- URL decode validation to catch encoded attacks
- Canonical path resolution to prevent symlink attacks
- Comprehensive path validation in all cleanup events

Cleanup improvements:
- S3RestoreJobFinished now handles all cleanup (helper container + all temp files)
- RestoreJobFinished uses new isSafeTmpPath() validation
- CoolifyTask dispatches cleanup events even on job failure
- All cleanup uses non-throwing commands (2>/dev/null || true)

Other improvements:
- S3 storage policy authorization on Show component
- Storage Form properly syncs is_usable state after test
- Removed debug code and improved error handling
- Better command organization and documentation
