sweep: pre-existing drift + matrix UDC entry + ignore 142MB EXE

Bundles drift left uncommitted from prior sessions and the UDC matrix
verify entry added today.

Drift items (all per session-progress.md, completed in earlier sessions
but never staged):

- playbook/check-bios.cmd (deleted, moved to BIOS/check-bios.cmd)
- playbook/migrate-to-wifi.ps1 (made no-op 2026-04-24 after the dnsmasq
  no-gateway fix removed the wired-NIC race that motivated it)
- playbook/preinstall/oracle/Install-Oracle11r2.cmd (post-OUI .ora copy
  added 2026-04-24)
- playbook/preinstall/oracle/tnsnames.ora (live tnsnames, 469 KB,
  deployed alongside the wrapper 2026-04-24)
- playbook/pxe_server_setup.yml (dnsmasq dhcp-option=3,6 commented,
  Oracle .ora deploy task added 2026-04-24)
- playbook/shopfloor-setup/BIOS/{check-bios.cmd, models.txt} (BIOS
  detection refinements)
- playbook/shopfloor-setup/Shopfloor/Force-Lockdown.bat
- playbook/shopfloor-setup/Shopfloor/Monitor-IntuneProgress.ps1
- playbook/shopfloor-setup/Shopfloor/SetShopfloorAutoLogon.bat (new)
- playbook/shopfloor-setup/Shopfloor/09-Install-PrinterInstallerMap.ps1
  (new, places PrinterInstallerMap.exe + Public Desktop shortcut at
  imaging time; manifest entry self-heals on tamper)
- playbook/shopfloor-setup/Shopfloor/lib/Show-IntuneDeviceQR.ps1 (new,
  standalone QR rendering for site that wanted just that piece)
- playbook/shopfloor-setup/gea-shopfloor-collections/{Install-eMxInfo.cmd.template,
  Restore-UDCData.ps1} (these were uncommitted in pre-rename Standard/;
  git mv didn't catch them because they were untracked at the time)
- docs/shopfloor-machine-imaging-guide.md (operator-facing how-to)

Matrix:
- common.test/matrix.json: add UDC verify entry to gea-shopfloor-collections
  row. Surfaces UDC silent-install issue (item H pending) instead of
  letting it pass silently.

.gitignore:
- PrinterInstallerMap.exe (142 MB) excluded. Track via LFS or stage on
  PXE server only - too big for regular git history. Untouched on disk
  so existing local copy still works.
