CALENDAR: Add configurable "Start week on" display setting in CALENDAR module (e.g., Monday vs. Sunday).

Affected users: All MYLE Calendar Users, including Administrative Staff/MOAs, Healthcare Professionals, and Clinic Administrators.

Task affected: CALENDAR tab — User Calendar Settings and weekly schedule views.

Impact: Visual confusion and cognitive friction. Clinics operating on a standard Monday-to-Friday schedule find the default Sunday-start view counterintuitive, leading to unnecessary scanning fatigue and potential scheduling errors when booking appointments early in the week.

Current state: Users are forced to adapt to the hardcoded default Sunday-start weekly view with no ability to toggle Monday as the start of the week in their user calendar settings.

Competition consideration: N/A
