Usability of Voting page for Meeting Proposals could be improved for mobile devices

Is your feature request related to a problem? Please describe.

Votes on mobile devices with narrow viewports are really hard to manage.

1. the submit button could be hidden behind the guest-box footer
2. to see all information, the user has to scroll horizontally and vertically
3. the previous votings are not clear marked (as previous votings), which can confuse the user when voting expecting the marks at his previous votings would change instantly with his actions on the form.

Describe the solution you'd like

1. hide the guest-box footer on this page
2. the current vote and the previous votings should be explicitly marked as those (by color, background, or by a label).
3. the current vote and the previous votings could be shown in different tabs on devices with narrow viewport, so that users can switch between them.

Describe alternatives you've considered

All considered alternatives did not lead to productive ideas.

Additional context

No response

Start by reproducing the Meeting Proposals Voting page on a narrow mobile viewport and locating its page and responsive layout entry points. Check the guest-box footer, scrolling behavior, and presentation of current versus previous votings; done means the submit action remains accessible, information is usable without problematic scrolling, and the voting states are clearly distinguished.
