UX: Improve assign modal design (#403)

Implements a new design that improves the user experience:

- add a clear cancel button
- add an indication the note is optional
- change the plus icon to a search icon
- show an error when the user tries to assign without choosing an assignee
- move suggestions to default search results
- focus search input when modal is displayed
