Members card

[BhushanSah]

Description

This PR adds a Members card to the Department Portal homepage. The card gives users a quick overview of the people connected to a department by showing the assigned Labor Coordinator(s) and a preview of department members.

Fixes #603
The card is meant to provide a simple summary on the homepage, while full personnel management will remain part of Issue #605.

Changes

• Added a Members card to the Department Portal homepage.
• Displayed assigned Labor Coordinator(s) for the selected department.
• Displayed a preview of department members.
• Connected the card to real department/personnel data instead of hard-coded values.
• Added a View Details button for navigating to the Manage Personnel page.
• Refactored the member display logic to make the route easier to read and maintain.

Notes

• Full personnel management functionality belongs to Issue Create Manage Personnel Page for the Department Portal #605.

Testing

• Verified that the Members card displays on the Department Portal homepage.
• Verified that Labor Coordinator(s) and department members are separated correctly.
• Verified that the page still loads when no personnel is assigned.
• Checked that the View Details button is present.

Supervisors may be excluded because of missing name fields

buildSupervisorDisplay() requires both FIRST_NAME and LAST_NAME. A supervisor who has a preferred name or legal name but is missing one of those fields may be removed from the displayed list completely.

There is no first name column in the database; the firstname attribute is linked to the preferred name to legal name method, which checks either.
