**As an** OpenProject user
**I want** search and help to take less space
**So that** I have more space on a smaller resolution screen.

**Acceptance Criteria**

- Help is depicted only by `icon-help`
- Search is depicted only by `icon-search`
- Search is expanded when clicked, consistent with openproject.org Begin of the insertion

The search form now behaves as following

- Keyboard
- Tab until collapsed search (icon) is focused, the search should expand and the input gains focus.
- Tab out of the input, icon will gain focus, search should NOT collapse.
- Press enter while icon is focused, search form should be submitted.
- Tab out of icon to help, search should collapse.
- Pressing s or modifier + 4 should expand the search.
- Mouse
- Click on collapsed magnifier, search should expand.
- Click on any other element other than input / icon, search should collapse.
- Click on the magnifier while the search is expanded, search should be submitted.
- Both
- Icon is now flipped when expanded (to resemble the previous state).End of the insertion
