[FRONTEND] Create Exec member info cards for About -> Exec team

[ashoomky]

Is your feature request related to a problem? Please describe

The About page displays 20+ exec team members, each shown with the same card layout. We need a reusable component so the layout stays consistent and the page is easy to update when execs change.

Describe the solution you'd like

Card displaying an exec team member's role, photo, name, degree, position, and years of experience.

Acceptance criteria:

• Renders: role label (e.g. "CO-PRESIDENT"), photo placeholder/image, name, degree, volleyball position, years of experience
• Used 20+ times on the About page — must handle missing fields gracefully
• Photo placeholder shown when image not provided

Props: role, name, degree, position, photo?

Describe alternatives you've considered

• Using shadcn's Card primitive as a base — viable but the layout is bespoke enough that a custom build is just as quick.

Additional context

Blocks the About page (Executives view).
