Tenant booking intervals now support whole-hour-only booking

What changed

Studios now have a tenant-level booking interval setting in admin. Public booking can stay on 30-minute intervals or switch to whole-hour-only start times and duration steps.

The same rule now applies consistently across the public booking form, dedicated add-on time pickers, alternative time recovery suggestions, the public master calendar, and admin schedule slot snapping and display.

Why this matters

• Studios that only want bookings on full hours no longer need to rely on staff instructions or manual correction.
• Customers now see a booking cadence that matches the studio’s real operating preference across forms and calendar entry points.
• Dedicated add-ons with their own time picker stay aligned with the tenant’s chosen booking rhythm instead of drifting back to half-hour choices.
• Studios are protected from misconfiguration because whole-hour mode is blocked when active public minimums still depend on half-hour steps.
