Changes

Solves #2183

last_login was natively updated by DRF only during authentication. However we persist session for multiple weeks leading to incorrect data.

This PR aims to update last-login on GET /me (once per session in a ideal world) with a 10min buffer. This could be multiple hours as we only show Today in the dashboard.

Additionally:

• Refactored LastLogin component in the frontend
  We used to show Never | within 30 days | with {xx} days if > 30 => Allowed to add Today Yesterday and number of days within 30 days (7 days ago e.g).
• Refactored Members Table in the frontend

How did you test this code?

• Added tests
• On the dashboard

One minor comment, otherwise LGTM.

Actually, having read the backend test, I have one request now.
