chore(deploy): align CTL deploy layout to server convention (C:\workspace\IIS, lowercase sites)

- Jenkinsfile: IIS_ROOT F:\IIS\ANTOOZA -> C:\workspace\IIS; sites/apppools antooza-api/antooza-admin; WORKER_ROOT C:\workspace\antooza
- phase1-setup-ctl.ps1: full provisioner (create apppools+sites+dirs+grants), server convention, ANCM warn-not-fail
- winsw/antooza-mail.xml: exec/workingdir -> C:\workspace\antooza\mail
