UX: improves assignee display on button and dropdown

- Changes the title attribute to display the name of the assignee
- Displays the assignee’s username in the row when  on mobile view
- Tweaks positioning to attempt good alignment
- Slightly increases icon size to have visually the same size than other topic footer buttons icons
