Docs: Add PowerShell comment-based help to all script modules

Adds standard PowerShell comment-based help blocks (synopsis and description) to all UI and common library script modules (`.psm1`) and the main UI entry point script (`.ps1`).

This improves maintainability and discoverability by documenting the purpose of each script file. Also removes various redundant or commented-out code blocks.
