Also add some JS to it to process any error we might have in the URI
(see #6893).

SAML2: render a comprehensible error page if something goes wrong

If an error happened while processing a SAML AuthN response, or a client
ends up doing a `GET` request to `/authn_response`, then render a
customisable error page rather than a confusing error.

Move get_time_of_last_push_action_before to the EventPushActionsWorkerStore

It's the same as in #6964 since it's the most likely cause of the bug
and that change hasn't been released yet.

This would break notifications about un-named rooms when processing
notifications in a batch.

Fixes #7054

I also had a look at the rest of the functions in
`EventPushActionsStore` and in the push notifications send code and it
looks to me like there shouldn't be any other method with this issue in
this part of the codebase.

Make sure that is_verified is a boolean when processing room keys

* Add type hints to logging/context.py
