[FEAT] user experience admin pages

[kristebo]

Proposed functionality
redisign of the admin pages

Use case
The admin pages are hard to use, long mouse moves, long workflows, high click count on simple tasks etc.

• Placement of edit and view should be near the title of the competitions
• breadcrumbs
• have a context where edit and admin is on each competition entry instead of a particular Admin buttun.

Backend changes
No changes to backend (???)
