📄 Description

Apply NormaliseHostname() before ValidateHostname() in ApplyHostnameFromHostInfo() and EnsureHostname() to sanitize hostnames with minor invalid characters instead of replacing them with generic identifiers like "invalid-abc123".

This allows hostnames like "My-PC!" to become "my-pc" rather than being rejected.

Fixes #2926
