[CLAUDE] Scripts: rewrite 4 deploy PS1 ASCII-only for PS 5.1 compat

PowerShell 5.1 reads .ps1 files as locale codepage (not UTF-8 no BOM),
which corrupts multi-byte Vietnamese chars and breaks parsing. Rewrote
setup-iis-sites.ps1, setup-ssl.ps1, setup-gitea-runner.ps1, deploy-all.ps1
as ASCII-only. Also renamed $Host param to $HostName in Ensure-Site to
avoid collision with PowerShell built-in $Host automatic variable.
