Add styling for overflowing table & dropdown robot

Bound modal box by container, remove !important

The important was introduced as a fix to
https://jira.coreos.com/browse/QUAY-881
However, after removal it does not seem to be necessary (Cannot
reproduce with the !important gone).

Adds bounding for the modal boxes & title

Joins the username/password for robot in box
