feat(status-page): add og:type and og:image Open Graph meta tags

Added additional Open Graph meta tags to status pages for better
social media sharing:
- og:type (set to "website")
- og:image (uses the status page icon if configured)

This complements the existing og:title and og:description tags.

Fixes #6514
