00-PreInstall: pre-stage udc_webserver_settings.json + firewall/NetFx3 hardening

Add staging block that copies udc_webserver_settings.json from the enrollment
share to C:\ProgramData\UDC during preinstall, mirroring the existing
udc_settings.json pattern. New PCs were imaging without UDC web server
config because the file was never wired into the imaging flow (only the
remote-maintenance task in powershell/remote-execution touched it).

Also folds in two prior uncommitted hardening blocks in the same script:
firewall NotifyOnListen=False (suppress Oracle OUI's listen-port prompt)
and NetFx3 pre-enable (Oracle 11.2's welcome path needs .NET 3.5).
