This will stop us repeatedly forgetting to add `novalidate` and
`autocomplete='off'` to our forms (which is how most of them are set
up).
It uses sensible defaults, based on how we most-commonly configure
forms:
- most of our forms are `post`ed (but this can be overridden)
- `autocomplete` should only be enabled where it makes sense, otherwise
it’s more annoying than useful (but this can be overriden)
- we should never be using HTML5 form validation because our own error
styles and messages are better
We didn’t make this self-service before because the pricing information
wasn’t published (ie we had to send it to services that asked for it).
Now that we publish pricing information in the app, there’s no reason
why services can’t make an informed decision about whether they want
international SMS or not.
So this commit:
- removes the platform admin button
- adds some radio buttons that our users can click with their mice
Users might be interested in international SMS. And when it’s fully
available, they’ll probably be able to control whether it’s on/off for
their service.
Until they point, the only way of getting it is to ask us. So let’s
make an in-the-meantime page that directs them to ask us, from the place
where they’d be able to do it themselves.
