CE-3493: Collapsable accordions

This ticket was about enabling accordions to be closed. But on deleting, updating, archiving a template a re-fetch template is automatically executed and resulting in parent component updating all tab content (for Status, Management and Admin tabs), resetting all state in these components. For admin tab this led all accordions to automatically close on successfully executed actions. Not a behavior we want.

My solution, which we have used before, was to let all tabs have a call to fetch template. The tabs will mostly use the cached template data and not make individually calls if not necessary.

This also includes some text changes and order of sections in Admin tab.
