Add FQDN support for network devices and fix printer installer map

## Printer Installer Map Fixes
- Fixed printer_installer_map.asp to pass printer IDs instead of generated names
- Fixed install_printer.asp dictionary key collision by using printerid

## Network Device FQDN Support
- Added fqdn column to machines table (migration script included)
- Updated device edit pages: deviceaccesspoint.asp, deviceserver.asp,
  deviceswitch.asp, devicecamera.asp
- Updated save_network_device.asp to handle FQDN in INSERT/UPDATE
- Updated network_devices.asp to display FQDN for Server, Switch, Camera
- Updated vw_network_devices view to include FQDN from machines table
- Added FQDN field to machine_edit.asp Network tab
- Updated savemachineedit.asp to save FQDN

## Printer Install Path Edit
- Added installpath field to displayprinter.asp Edit tab
- Updated editprinter.asp to save installpath changes

## Documentation
- Added IIS log location to CLAUDE.md

## Production Migration
- sql/add_fqdn_to_machines.sql - Run on production to add column and update view
