On the support page we now promise that we’ll:
- look at tickets within half an hour
- reply within one working day
The thanks page was always promising a reply within half an hour, during
business hours or an emergency. This commit changes the ‘thanks’ page to
be consistent with the support page.
In pages specific to a service (e.g. dashboard and sub pages) the title
needs to distinguish which service it applies to. This is mainly to give
context to screen reader users who could be managing multiple services.
Implementing this uses template inheritance:
`page_title` includes `per_page_title` includes `service_page_title`
‘GOV.UK Notify’ is inserted into every page title.
Pages that set `service_page_title` get the service name inserted too.
Generally I prefer confirmation pages to the flash message thing
(they’re harder to miss). So this commit adds one.
It also adds some logic to this page, so that, depending what the user
has told us about the thing they’ve submitted, we can tell them how
quickly to expect a response.
