[Enhancement] Improve this error message by appending two checks: form security failed because of a token mismatch

[atom-box]

When this error occurs in the client browser:
The form security failed because of a token mismatch. Please reload the form and check that your cookies are on
Part of the error message could the following:

1. In the browser, check whether cookies are on. Just run this and modify the error message:

if (navigator.cookieEnabled) {
    console.log("Cookies are enabled.");
} else {
    console.log("Cookies are disabled.");
}

2. In the backend send a check for SSL (a cause of this error). The logic already exists: it is part of Matomo's System Check, in the Admin >> Diagnostics

This is a high frustration error for users as it keeps them logged out of their Matomo. Recently a team of 5 users, staring down a promised deadline, were all locked out for 5 days and 5 emails because of this error.
