Clint Branham f6a2f843db docs: update cmdlet help via platyPS merge, fix generate-help.ps1
- generate-help.ps1: rewritten to use Update-MarkdownHelp (merge) by
  default, preserving hand-written descriptions and examples. Only
  New-MarkdownHelp on genuinely new cmdlets. -Force flag for full regen.
- docs/cmdlets: parameter metadata updated via platyPS merge, CRLF
  normalized to LF
- Removed stale Send-PveIso.md (cmdlet renamed to Send-PveFile)
