`evaluate-response` should be a single form with options

[zner0L]

Right now, the evaluate response page shows the options as different separate forms:

platform/src/pages/p/[token]/evaluate-response/index.astro

Lines 45 to 53 in 6f62735

	(['promise', 'denial', 'none'] as const).map((r) => (
	<form class="radio-wrapper" method="POST" action={absUrl(`/p/${token}/evaluate-response/${r}`)}>
	<button
	type="submit"
	class:list={['radio-label', { disabled: r === 'none' && !deadlineExpired }]}
	disabled={r === 'none' && !deadlineExpired}>
	{t('evaluate-response', `reponse-${r}`)}
	</button>
	</form>

However, semantically this should be an option input which submits a single form when clicked/focus is lost. This would require us to explain to users that a context change will occur (https://www.w3.org/TR/2016/NOTE-WCAG20-TECHS-20161007/G13).

But instead, we could also provide a separate submit button altogether (labeled "Continue" or something), which I think is better practice anyway (https://www.w3.org/TR/2016/NOTE-WCAG20-TECHS-20161007/G80). At least was a bit startled after clicking one of the links and immediately starting an analysis.

I also suggest redirecting to the /p/ page instead of erroring, if the user accesses the page with a wrong proceeding status.
