Steps:

1 . Go to personalization

2. go to Models

3. Edit one example 

Result:

Wrong styles of Edit page. 

1. Lack of primary button style " save"
2. Lack of " cancel Button"
3. Wrong weight of content (is being done in other PR)
4. Wrong styles of drag and drop (sidebar fixes done in other PR)
5. The library hasn't fixed to screen high
6. Lack of "Search..." as placeholder and icon " search" in search

Expected results 

1. Save should be a primary button
2. We should have the " cancel" action as a third button next to " save and close"
3. Weight content should be based on templates from all. system like in https://master-7rqtwti-v5p5smejfqk2u.fr-4.platformsh.site/admin/contenttypegroup/5/contenttype/add
4. Styles and behavior should be consistent ( copied) from https://master-7rqtwti-v5p5smejfqk2u.fr-4.platformsh.site/admin/contenttypegroup/5/contenttype/add  or https://master-7rqtwti-v5p5smejfqk2u.fr-4.platformsh.site/admin/content/edit/draft/130/1/eng-GB
5. Add "Search..." placeholder and icon search to search input
