Rename -Source parameter to -Video in Create-Clip.ps1 and Create-PillarBox.ps1 for consistency with other scripts, updating all internal variable names (sourcePath->videoPath, sourceFull->videoFull) and documentation references, while preserving .skip marker handling and parameter forwarding logic in Create-Clip.ps1 and maintaining default -Target derivation and effect naming in Create-PillarBox.ps1
