Greptile Summary

This PR removes the "Experimental" label from the relationship column type in the database table UI, promoting it to a stable, production-ready feature.

• Removes the titleBadge prop from the SideSheet in +layout.svelte that conditionally showed "Experimental" when creating a relationship column.
• Removes the inline <div class=\"tag\">Experimental</div> badge from the modal title slot in columns/edit.svelte when editing a relationship column.

Confidence Score: 5/5

Safe to merge — two small, isolated UI-only removals with no logic changes.

Both changes are purely cosmetic label removals. No logic, state, or API surface is touched. A quick grep confirms no other relationship-related "Experimental" badges remain in the codebase.

No files require special attention.
