As a preliminary step for including graphs of StreamCount data in our
analytics pages, add API support for fetching the chart data.
Care is taken to limit access to streams that the current user has
access to, which isn't necessary in similar views where the current
user is a server administrator by assumption.
Fixes part of #19653.

_default_manager is the same as objects on most of our models. But
when a model class is stored in a variable, the type system doesn’t
know which model the variable is referring to, so it can’t know that
objects even exists (Django doesn’t add it if the user added a custom
manager of a different name). django-stubs used to incorrectly assume
it exists unconditionally, but it no longer does.

Translators benefit from the extra information in the field names, and
need the reordering freedom that isn’t available with multiple
positional fields.

Adds the count of users with the role of guest to the stats view
`page_params` via a database query. This information is then added
to the summary statistics section of the analytics page after being
formatted by `stats.js`.
Creates Bassanio as a guest user in the database for the analytics
realm.
Fixes#20162.
Adds the realm's used storage space for attachments to the stats
view `page_params`. This information is then added to the summary
statistics section of the analytics page after being formatted by
`stats.js`.
Uses the emoji test image to create an `Attachment` in the database
for the analytics realm. Even though it doesn't create a message
to claim the attachment, it still is sent as storage space used
data for the analytics `/stats/` page.
Decorators like `require_server_admin_api` turns user_profile into a
positional-only parameter, requiring the callers to stop passing it as a
keyword argument.
Functions like `get_chart_data` that gets decorated by both
`require_non_guest_user` and `has_request_variables` now have accurate
type annotation during type checking, with the first two parameters
turned into positional-only, and thus the change in
`analytics.views.stats`.

This makes `has_request_variables` more generic, in the sense of the return
value, and also makes it more accurate, in the sense of requiring the
first parameter of the decorated function to be `HttpRequest`, and
preserving the function signature without using `cast`.
This affects some callers of `has_request_variables` or the callers of its
decoratedfunctions in the following manners:
- Decorated non-view functions called directly in other functions cannot
use `request` as a keyword argument. Becasue `Concatenate` turns the
concatenated parameters (`request: HttpRequest` in this case) into
positional-only parameters. Callers of `get_chart_data` are thus
refactored.
- Functions to be decorated that accept variadic keyword arguments must
define `request: HttpRequest` as positional-only. Mypy in strict mode
rejects such functions otherwise because it is possible for the caller to
pass a keyword argument that has the same name as `request` for `**kwargs`.
No defining `request: HttpRequest` as positional-only breaks type safety
because function with positional-or-keyword parameters cannot be considered
a subtype of a function with the same parameters in which some of them are
positional-only.
Consider `f(x: int, /, **kwargs: object) -> int` and `g(x: int,
**kwargs: object) -> int`. `f(12, x="asd")` is valid but `g(12, x="asd")`
is not.

Luckily `QuerySet` supports type variables. This allows us
to type table_filtered_to_id more accurately.

Adds request as a parameter to json_success as a refactor towards
making `ignored_parameters_unsupported` functionality available
for all API endpoints.
Also, removes any data parameters that are an empty dict or
a dict with the generic success response values.
Since mypy doesn't accept redefinition of the same variable within the
same scope, we need to use type annotations with Union to correctly
type aggregate_table. Note that the type cast is necessary for mypy to
narrow the type of aggregate_table.
For types like `Union[Realm, UserProfile, Stream]` and
`Union[AnonymousUser, AbstractBaseUser]`, we need assertions to
tell mypy which type we would be expecting.
