Change Color of "Joined" Text on Members Page

As a user, I want the "Joined" text on the Members page to have a different color, so it doesn't appear as a clickable call-to-action (CTA), which can cause confusion.

**UI Placement:**
The "Joined" text should appear in a non-CTA color to avoid indicating interactivity where none exists.

**ACCEPTANCE CRITERIA:**

- **Color Change**: Update the "Joined" text color to a black that does not resemble a clickable link or CTA. The new color should ensure readability while clearly indicating that the text is not interactive.
- **Page to Update**: Members page - Ensure that the "Joined" text reflects the new color across all entries on this page.
- **Consistency**: The same non-CTA color should be applied uniformly across any other pages or sections where the "Joined" text might appear.
