Shopfloor: Configure-PC tool, machine-number logon prompt, execution order fixes

New tools:

Configure-PC.bat/.ps1 - Interactive desktop tool for SupportUser to
configure a shopfloor PC after imaging. Two sections:
  1. Machine number: if UDC/eDNC are still at placeholder 9999, prompt
     to set the real number right now (updates UDC JSON + eDNC registry,
     restarts UDC.exe with new args).
  2. Auto-startup toggle: pick which apps start at user logon from a
     numbered list (UDC, eDNC, Defect Tracker, WJ Shopfloor, Plant Apps).
     Creates/removes .lnk files in AllUsers Startup folder. Toggle UI
     shows [ON]/[  ] state, safe to re-run anytime. Plant Apps URL
     resolved from .url file at runtime with hardcoded fallback to
     https://mes-wjefferson.apps.lr.geaerospace.net/run/...
  3. Item 6 in the toggle list: register/unregister a "Check Machine
     Number" logon task for standard (non-admin) users. When enabled,
     the task fires at every logon, checks for 9999, pops an InputBox
     if found, updates both apps, then unregisters itself on success.

Check-MachineNumber.ps1 - The logon task script. Runs as the logged-in
user (needs GUI for InputBox), not SYSTEM. Writing to ProgramData + HKLM
is possible because 02-MachineNumberACLs.ps1 pre-grants BUILTIN\Users
write access on the two specific targets during imaging.

02-MachineNumberACLs.ps1 - Standard type-specific script (runs after
01-eDNC.ps1). Opens C:\ProgramData\UDC\udc_settings.json for Users:Modify
and HKLM:\...\GE Aircraft Engines\DNC\General for Users:SetValue. Narrow
scope, not blanket admin.

Execution order fixes in Run-ShopfloorSetup.ps1:

The dispatcher now has two lists: $skipInBaseline (scripts NOT run in the
alphabetical baseline loop) and $runAfterTypeSpecific (scripts run
explicitly after type-specific scripts complete). This fixes the bug where
06/07 ran before 01-eDNC.ps1 installed DnC, so eDNC/NTLARS shortcuts were
silently skipped.

New execution order:
  Baseline: 00-PreInstall, 04-NetworkAndWinRM (skipping 05-08 + tools)
  Type-specific: 01-eDNC, 02-MachineNumberACLs
  Finalization: 06-OrganizeDesktop, 07-TaskbarLayout

06 internally calls 05 (Office shortcuts, Phase 0) and 08 (Edge config,
Phase 4) as sub-phases, so they also benefit from running late. Office
isn't installed until after the first reboot (ppkg streams C2R), so 05
no-ops at imaging time but succeeds when 06's SYSTEM logon task re-runs
it on the second boot. 08 resolves startup-tab URLs from .url files
delivered by DSC (even later); same self-heal via the logon task.

Other fixes in this commit:

- OpenText Setup-OpenText.ps1 Step 4: exclude WJ_Office.lnk, IBM_qks.lnk,
  mmcs.lnk desktop shortcuts (matching the Step 3 .hep profile exclusion
  from the previous commit). Removes stale copies from prior installs.
- 05-OfficeShortcuts.ps1: widened Office detection to 6 path variants
  covering C2R + MSI + Office15/16, with diagnostic output on miss.
- 06-OrganizeDesktop.ps1: removed Phase 3 (desktop-root pin copies for
  eDNC/NTLARS) so shortcuts live in Shopfloor Tools only, not duplicated
  at root. Emptied $keepAtRoot. Added Phase 0 (call 05) and Phase 4
  (call 08). Lazy folder creation + empty-folder cleanup. Scheduled task
  now runs as SYSTEM (was BUILTIN\Users with Limited which failed the
  admin check). Added NTLARS to 07's taskbar pin list.
- 08-EdgeDefaultBrowser.ps1: Plant Apps URL fallback hardcoded from
  device-config.yaml.
- All new scripts have Start-Transcript logging to C:\Logs\SFLD\ with
  timestamps and running-as identity.
- Run-ShopfloorSetup.ps1: Start-Transcript + Stop-Transcript wrapping
  entire dispatcher run, writes to C:\Logs\SFLD\shopfloor-setup.log.
  Configure-PC.bat added to SupportUser desktop copy list.
