Fix PowerShell parameter conflicts by renaming Verbose to VerboseOutput

- Fixed parameter conflicts in sf-data-export.ps1, sf-data-import.ps1, sf-retrieve.ps1, and sf-test-run.ps1
- Renamed conflicting \ parameter to \ to avoid conflicts with PowerShell's built-in -Verbose common parameter
- Added proper parameter sets to ensure -Help parameter works correctly in all scripts
- Added -hp aliases where needed for consistency across all scripts
- All scripts now properly support help functionality without parameter conflicts

This resolves issues where scripts would fail with 'A parameter with the name Verbose was defined multiple times' error.
