UX tweaks

• Make the button "Optimize text with AI" appear only from 3 words onwards
• If there are no questions yet, and you are on a desktop, place the plus button in the middle of the page
• Add a checkbox in the DSGV popup to accept the privacy policy
• Set the dark mode as default
• Reduce the header options: In the participant role, show the brainstorming button only when there is a brainstorming session
• Reduce the header options: Show the topic cloud button only if there are keywords to questions
• Remove the day|night mode if it does not work in all browsers
• Place the user online icon in the header when on the Q&A page on a desktop
• Do not count brainstorming submissions to the question counter
• Remove the tooltips from the sort menu
• Tooltips for the editor formatting buttons
• Show the text optimization button only from the fourth word onwards
• More animations and effects were requested, such as a question disappearing sideways into moderation or a new question being pushed in from the left
• If the text optimization does not yield a result, give a corresponding hint in the snack bar
• In the participant view, show the app in a smartphone iframe (as in Chrome DevTools). See "arsnova.click"'s editor preview.
• Initially, put the plus button on the brainstorming page animated in the middle like on the Q&A page and add the subtitle "Enter your idea!"
• Set the user icon ("person") as the background image for a participant's questions
• Unmask Bold markup in Quill, otherwise spaCy will get swallowed up
• Additional column in the bonus export, that names the user (if registered his mail address, if name given this name, otherwise anonymous)
• Apply color matching to the options label as well:
• Create an entry "Bonus archive" (if room creator or moderator) in the options menu of the Q&A page
• Create an entry "Bonus archive" (if room creator or moderator) or "My bonuses" (if participant) in the options menu of each room (see screenshot)
• Create an entry in the options menu of each room with the direct link to the room (see screenshot)
