kms-website: public scripts + sanitized copy + slack notifier

- static/scripts/{setup-kms.ps1,kms-bootstrap.ps1}: public, internet-friendly
- Drop \\nas.viktorbarzin.lan\\Emo shared\\ refs (internal SMB share, leaks personal name)
- Reframe LAN section as optional auto-discovery for self-hosters
- Add privacy + legality FAQs
- Quick Start uses one-liner: iwr | iex against /scripts/kms-bootstrap.ps1
- bootstrapURL now points at site-relative /scripts/
