PC profiles: per-type/sub-type config + Standard Timeclock/Machine menu

Adds a pcProfiles section to site-config.json that lets each PC type (and
optional sub-type) override startupItems, taskbarPins, and desktopApps.
Scripts resolve: pcProfile > site-wide default > hardcoded fallback.

New shared helper: Shopfloor/lib/Get-PCProfile.ps1
  Dot-sourced by consuming scripts. Reads pc-type.txt + pc-subtype.txt,
  builds a profile key (e.g. "Standard-Machine"), and looks it up in
  site-config.json pcProfiles. Exports $siteConfig, $pcType, $pcSubtype,
  $profileKey, $pcProfile for the caller to use.

  Replaces the inline Get-SiteConfig function that was copy-pasted into
  each script. Scripts now do:
    . "$PSScriptRoot\lib\Get-PCProfile.ps1"
  instead of duplicating the loader.

startnet.cmd changes:
  - Added Lab as PC type option (7)
  - Standard now has a sub-type menu: Timeclock / Machine
  - Display sub-type menu also writes PCSUBTYPE for consistency
  - pc-subtype.txt written alongside pc-type.txt when sub-type selected
  - site-config.json copied from enrollment share to W:\Enrollment\

site-config.json v2.0:
  - New pcProfiles section with profiles for:
    Standard-Timeclock, Standard-Machine, CMM, Genspect, Keyence,
    WaxAndTrace, Lab, Display-Lobby, Display-Dashboard
  - CMM/Genspect/Keyence/WaxAndTrace profiles have TODO comments for
    type-specific apps (placeholder with WJ Shopfloor baseline only)
  - Lab/Display profiles have empty startupItems and desktopApps
  - Top-level startupItems/taskbarPins/desktopApps remain as site-wide
    defaults (used when no profile matches)

Updated scripts:
  06-OrganizeDesktop.ps1 - desktopApps from profile > site > hardcoded
  07-TaskbarLayout.ps1   - taskbarPins from profile > site > hardcoded
  08-EdgeDefaultBrowser.ps1 - uses shared profile loader
  Configure-PC.ps1       - startupItems from profile > site > hardcoded
