[meta]: Common polishing fixes for beta version 6

[mauro-balades]

• (Onboarding): The orange background color seems nice, but the animations seem to speedy, maybe ease out + 0.5s would be better. #4036

• (Onboarding): There is too much space between the header and the options, also, there is a random white triangle in the corner. #4037
  

• (Onboarding): Buttons don't use pointers as the cursor and don't have fade animations, they are just abrubptly inverted. #4038
  

• (Onboarding): Selection indecator for option is to faint to properly see which option is selected #4039

• (Onboarding): DuckDuckGo and Wikipedia look selected when its actually Google that is selected #4040
  

• (Sidebar) Inconsistent padding on sidebar buttons #4052

• (Sidebar): The emojis should be bigger when you have so much space, also, a search function would be nice #4041

• (Sidebar): The workspace icons are too small #4042

• (Sidebar): If this is the sidebar, what is that, the toolbar? I see it refered to as either the sidebar or toolbar. Just choose one (i recommend sidebar, because toolbars are usally just icons). #4043

• (Sidebar): The padding of the popup dialog is inconsistent, it should be larger anyway. #4044

• (Sidebar): When you first open zen, you can click this button. But if you click it, it changes the layout and the option disapeered, even when switching back the layout. (also this says sidebar again? use the sidebar icon like every other app and Zen Sidebar can use a different icon). #4045

• (Sidebar): Pressing restore defaults seems to have prevented me from closing this. Also the overflow menu popup is not in the zen toolbar, just pointing at nothing. #4046

• (Sidebar): Clicking the Zen Sidebar option doesn't seem to close it. Just replay the animation #4049

• (Sidebar): Hovering over this button in the Protections popup, makes the background black (again, with no animation). #4048

• (Sidebar): The animations of these sidebars hide the rounded corner #4050

• (Sidebar): The options menu is too close to the traffic lights #4054

• (Sidebar): The button in this panel uses a completely different design for some reason #4055

• (Sidebar): The toggle is grayed out when you hover it? #4047

• (Settings): If the window is too small, the settings is cut off, just hide the sidebar (in settings) #4051

• (Sidebar): The emojis should be bigger when you have so much space, also, a search function would be nice #4041 will be automatically closed once we merge Adds search to icons [DRAFT] #3963
