The frontend should work without having JS enabled. JS will enhance the
experience but should under no circumstance be necessary.
To achieve this, the entire entry system has been turned into a form
that posts its values to a new backend path specifically made to take
form responses. Instead of returning an API response, it also redirects
the browser to either the voting page on successful creation or the
frontpage with a bunch of get parameters that are used to prefill the
form in a server-side rendering process.
An error parameter is also given but there is no way to display said
error for now.
