# setup-new-iis-sites.ps1
# Creare site-uri IIS noi pentru infrastructura Dokploy ROMFAST
#
# Site-uri create:
#   1. roa-qr.romfast.ro  → proxy la LXC 103 Traefik (pdf-qr-app)
#   2. *.roa.romfast.ro   → proxy wildcard la LXC 103 Traefik (toate app-urile Dokploy)
#
# Rulat pe VM 201 (roacentral) ca Administrator
# Prerequisite: IIS URL Rewrite Module instalat
