Johan Sandoval 1c531bc2ab Generalize USMT Dash and add a containerized demo mode

Remove all environment-specific data and make the dashboard adoptable
anywhere, then add a demo that runs the real PowerShell services.

- Strip cached device data, internal knowledge-base articles and
  screenshots, server/site names and the old project notes; replace the
  knowledge base with generic sample articles and diagrams
- Move every environment value into Config/usmt-dash.psd1
- Route all infrastructure access in the worker and Get-Software.ps1
  through a provider (Providers/SCCM.ps1), with a config-driven asset
  inventory view instead of a hard-coded custom class
- Add Providers/Demo.ps1: a deterministic simulated fleet whose
  migrations progress in real time, and Demo/New-DemoData.ps1 to seed it
- Server: -Demo makes the API read-only; add get-config and get-logs;
  serve static files only from web/, Documentation/ and an allowlist of
  Data/ files with a path-traversal guard; gzip large responses
- Mirror both services' console output to Data/Logs via a Write-Host
  proxy, and add a terminal panel to the dashboard that streams it
- Demo sandbox (web/demo/demo.js): visitor changes to tags, articles and
  images are kept in the visitor's browser and echoed in the terminals;
  nothing a visitor does reaches the server
- Vendor marked, highlight.js and html2pdf.js instead of loading CDNs
- Dockerfile and compose file for hosting the demo (Coolify-ready)

Device Storage Remediation

USMT needs free space on the source device for its working files. Devices under about 15 GB free often fail the backup. USMT Dash shows free space in the USMT Status table.

1. Remove stale profiles

Press Win, type About your PC, open Advanced system settings.
Under User Profiles click Settings.
Delete profiles named Account Unknown and profiles of users who no longer use the device. Never delete the current user's profile.

2. Clear temp folders

Remove-Item "$env:WinDir\Temp\*" -Recurse -Force -ErrorAction SilentlyContinue
Remove-Item "C:\Temp\*" -Recurse -Force -ErrorAction SilentlyContinue

3. Clear the ConfigMgr cache

Control Panel > Configuration Manager > Cache tab > Configure Settings > Delete Files > Delete persisted content.

4. Rebuild the search index (if Windows.edb is huge)

Stop-Service WSearch -Force
Remove-Item "C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb" -Force
Start-Service WSearch

5. Disk Cleanup

Run cleanmgr /sageset:1 once to tick every category, then cleanmgr /sagerun:1.

After cleanup, use Force Update in USMT Dash (click the status button in the top bar) to refresh the free-space reading.
