Enhance Wait-PSFRunspaceWorkflow with new ShowProgress parameters

[fslef]

This pull request enhances the Wait-PSFRunspaceWorkflow PowerShell function by introducing an optional progress display feature. This new capability allows users to monitor the workflow's real-time progress, including per-runner and per-queue/item statistics, across all supported waiting modes. The changes are focused on improving usability and visibility during long-running workflow operations.

Progress reporting enhancements:

• Added a new ShowProgress switch parameter to the function, enabling users to opt-in for dynamic progress output during workflow waits.
• Implemented detailed progress tracking for each workflow and its runners, showing elapsed time, completion statistics, and queue/item details using nested Write-Progress calls.
• Integrated progress reporting logic into all workflow waiting modes (Closed, WorkerClosed, Count, WorkerCount, Reference, and WorkerReference), ensuring consistent and informative output regardless of how completion is measured. [1] [2] [3] [4] [5]

These improvements make it much easier for users to track the status and throughput of complex runspace workflows in real time.Refactor Wait-PSFRunspaceWorkflow function to improve parameter handling and add progress reporting.
