feat(backend): introduce vitals queue workflow

Description

This merge request introduces a dedicated Vitals Queue and the vitals workflow state to ensure patients undergo mandatory vitals checks before entering a doctor’s consultation queue.

Previously, patients were directly placed into a doctor’s waiting queue upon assignment, bypassing the vitals stage. This change enforces a structured and predictable patient flow and prevents doctors from seeing patients whose vitals are not yet recorded.

Summary of Changes

• Introduced a new queue state vitals
• Queue endpoints and WebSocket rooms now include patients with status vitals and consultation_completed.
• Patients are now placed in the Vitals Queue immediately after assignment
• Automatic transition from vitals → waiting after successful vitals recording
• Doctors only see patients who are consultation-ready (waiting or in_consultation), while the Vitals Queue view shows patients in vitals.

Checklist

• Code follows project API guidelines.
• The feature has been fully implemented.
• Tests for the new feature are included and passing.
• Impact on existing functionality has been considered.
• Code adheres to project coding standards.
