[RT-2863] Show container status in the details page of an exploit

[blu3r4y]

Acceptance Criteria:

When I am running my steps, I want to feel confident that my exploit container is still alive and running, therefore I want to see its live status at any given time.

Tasks:

• Design and implement a container status badge on the details page
• In the backend, also return the container startup time with the status endpoint
• Poll the container status endpoint every ~ 2 seconds when I am on the page
• With a countdown show how long the container is running already
  • Get this information from the status endpoint
