An automatic validation has been added when assigning a service to a worker from the appointment management section.
With this improvement:
• The system verifies whether the worker already has another appointment within the same date and time range.
• A warning message is displayed when a scheduling conflict exists.
• The conflicting appointment details are shown (date, time, status, and client).
• The system prevents assigning services that would create scheduling conflicts.
This validation improves schedule control, prevents operational conflicts, and ensures more organized service planning.
