Copilot 296d8f87b6 Fix: Prevent backup directory creation during dry runs (#41460)
## Summary

This PR fixes an issue where the backup folder was being created
unnecessarily when users navigated to the General tab in PowerToys
Settings, even when no actual backup had been triggered.

## Problem

When opening PowerToys Settings and navigating to the General tab, the
backup directory (default: `~/Documents/PowerToys/Backup`) was
automatically created, even though no backup operation had been
performed. This caused confusion for users setting up PowerToys on new
devices, as they would always need to manually clean up the unwanted
default folder when configuring a custom backup path.

## Root Cause

The issue occurred because:
1. Loading the General tab triggers `RefreshBackupRestoreStatus()` 
2. This calls `DryRunBackup()` to check backup status
3. `DryRunBackup()` executes `BackupSettingsInternal()` with
`dryRun=true`
4. However, the directory creation logic (`TryCreateDirectory`) was
running regardless of the dry run flag

## Solution

The fix ensures that directory creation only happens during actual
backup operations:

**Primary Change**: Wrapped backup directory creation in a dry run
check:
```csharp
// Only create the backup directory if this is not a dry run
if (!dryRun)
{
    var dirExists = TryCreateDirectory(settingsBackupAndRestoreDir);
    if (!dirExists)
    {
        Logger.LogError($"Failed to create dir {settingsBackupAndRestoreDir}");
        return (false, $"General_SettingsBackupAndRestore_BackupError", "Error", lastBackupExists, "\n" + settingsBackupAndRestoreDir);
    }
}
```

**Consistency Change**: Also moved temporary directory creation inside
dry run checks to maintain consistent behavior throughout the backup
process.

## Impact

-  **General tab loading**: No longer creates unwanted backup
directories
-  **Actual backup functionality**: Remains completely unchanged
-  **User experience**: Clean setup without unwanted default folders
-  **No breaking changes**: All existing backup/restore features work
as before

## Testing

Created comprehensive tests to validate:
- Dry runs (General tab loading) don't create directories
- Actual backup operations create directories as expected
- No regression in existing backup/restore functionality

Fixes #38620.
