CALENDAR: Expand CALENDAR patient search to include secondary email addresses

Affected users: MOAs and administrative staff who manage scheduling, patient inquiries, and daily clinic bookings.

Task affected: Calendar module — Quick patient search bar workflow (including the "Show Advanced Search Results" interface) used when booking or modifying appointments.

Impact: Intermittent but significant administrative friction and communication delays. When a patient can only provide an alternative email, the calendar's search bar fails to locate their file. This forces staff to contact the patient again just to request different identifiers, stalling the scheduling process and lowering administrative efficiency.

Current state: It is currently impossible to look up patients by secondary email addresses within the CALENDAR tab. Even activating the "Show Advanced Search Results" option does not index these specific communication fields, leaving users with no workaround inside the scheduling module.

Competition consideration: N/A
