ui: Fix top margin for content containers

Currently, when a message is shown at the top or in users and groups page, The
top margin is too short. Increase it to 25px from 5px. Also:

- Don't use the .thumbnail class for containers as this does not match the
  semantics. Create and use class .contain-container.

- Also create class .card-container for all container containing cards. Unused
  for now.

- Indentation fixes.

- Remove duplicated rule.
