FEAT: Add All Facilities to Facility Drop Down for Department Admins

[jtucholski]

Description

Allow Department Admins to view data across all facilities by adding an "All Facilities" option in the facility dropdown.

User Stories

1. Viewing All Facilities

• As a Department Admin, I want an "All Facilities" option in the dropdown so I can view data across all facilities in a single view.

2. Facility-Level Context

• As a Department Admin, I want tables (e.g., Residents, Admins) to include a Facility Name column when "All Facilities" is selected so I can identify which facility each record belongs to.

Acceptance Criteria

• The facility switcher dropdown includes an "All Facilities" option, visible only to Department Admins.
• Dashboards (Knowledge Insights, Learning Insights, and Operational Insights) no longer include a facility filter.
• When "All Facilities" is selected:
  • The Residents page includes a Facility Name column.
  • The Admins page includes a Facility Name column.
  • Dashboards show data in aggregate.

Additional Context

• "All Facilities" should not be treated as a real facility.

Open Questions

• When adding a new user while "All Facilities" is selected, how should the Department Admin assign a facility?
  • Possible options:
    • Require the Admin to select a facility in the modal window.
    • Disable facility-specific actions when "All Facilities" is selected.

Out of scope

• How the Knowledge Center handles "All Facilities" should be out of scope for this task.
