Draft: feat: Implement Patient Status Dashboard with Visit Progress and Queue Tracking

This MR introduces the Patient Status Dashboard, which allows patients to track their visit progress during the medical camp workflow.

The dashboard dynamically displays the patient's current stage in the visit journey and provides detailed information recorded during each stage.

Added Doctor Consultation stage to the workflow.

Corrected the stage order to match the actual patient journey:
