Table reservations - UI bugfix

Resolved a visual issue related to table conflicts, which occur when one or more tables are already allocated to an arrived or seated booking and a second booking using the same table(s) is also marked as arrived or seated.

In this situation, the team member is asked to correct the conflict by reassigning tables on the second booking.

Although an error message was correctly shown in this scenario, it was not cleared after the conflict was resolved, causing the error message to appear on bookings without issues when changing table assignment.

The error state is now cleared correctly when resolving the conflict.
