Add PC-machine relationships API and report, fix shopfloor dashboard

- Add getPCMachineRelationships API endpoint for PC-to-machine mappings
- Add pcmachinerelationships.asp report page with copy table/CSV/JSON export
- Fix shopfloor dashboard to immediately hide deactivated notifications
- Add Firewall (machinetypeid 46) support to network device pages
- Add model migration warning banner to networkdevices.asp
- Create SQL script for hybrid model/machine type view

+-- PURPOSE: Update vw_network_devices to use model's machinetypeid (with fallback)
+-- DATE: 2026-01-29
+--
+-- DESCRIPTION:
+-- This update changes vw_network_devices to prefer model.machinetypeid over
+-- machines.machinetypeid (deprecating the latter). Uses a hybrid approach:
+-- - If model has a valid network device machinetypeid (16,17,18,19,20,46), use it
+-- - Otherwise fall back to machines.machinetypeid for backward compatibility
+--
+-- Also adds Firewall (machinetypeid=46) to the list of network device types.
