# What this PR does
This PR:
- adds a few attributes to paginated API responses
- removes channel filter "send demo alert" internal API endpoint + tests
(this endpoint was marked as deprecated + not consumed by the web UI)
With the new paginated API response schema, the web UI will no longer
need to:
- hardcode `ITEMS_PER_PAGE` for each table
- manually calculate total number of pages
(these two things ☝️ will be done in
https://github.com/grafana/oncall/issues/2476)
For `GET /api/internal/v1/alertgroups` the response will now look like
this:
```diff
{
"next": <url> | None,
"previous": <url> | None,
"results": [],
++ "page_size": <int>
}
```
For all other paginated API responses, the response will now look like:
```diff
{
"count": <int>,
"next": <url> | None,
"previous": <url> | None,
"results": [],
++ "page_size": <int>,
++ "current_page_number": <int>,
++ "total_pages": <int>
}
```

# What this PR does
- Adds [`mypy` static type checking](https://mypy-lang.org/) to our CI
pipeline. Currently there is still a **ton** of errors being returned by
the tool, as we'll need to fix pre-existing errors. I think we can
slowly chip away at these errors in small PRs, doing them all in one
large PR is likely very risky.
- Also, this PR starts chipping away at one of the main type errors that
we have which is accessing the `datetime` class (from the `datetime`
library) or `timedelta` function on the `django.utils.timezone` module.
Basically we should be instead accessing these two objects from the
native `datetime` module. This makes sense because the [`__all__`
attribute](https://github.com/django/django/blob/main/django/utils/timezone.py#L14-L30)
in `django.utils.timezone` does not re-export `datetime` or `timedelta`.
- splits `engine` dependencies out into `requirements.txt` and
`requirements-dev.txt`
