chore(github): generic NETLOGON paths, remove mirror scripts

Replace \\B26\\NETLOGON with \\dc.contoso.local\\NETLOGON.
Remove scripts/ mirror tools and tools/Push-KalinamallOnly.ps1.
Sanitize login_monitor.settings.example (placeholders, no secrets).
Simplify update-rdp-monitor.ps1 to use origin remote only.
Keep dev tooling under tools/ only.
