fix(web): correct spec social metadata

Summary

• Use LiveView’s live title helper so spec titles update correctly during client-side navigation.
• Normalize the shared feed dropdown icon button sizing so it aligns with adjacent spec page controls.
• Add coverage for public spec head metadata for anonymous visitors.
