Previously, we type the model fields with explicit type annotations
manually with the approximate types. This was because the lack of types
for Django.
django-stubs provides more specific types for all these fields that
incompatible with our previous approximate annotations. So now we can
remove the inline type annotations and rely on the types defined in the
stubs. This allows mypy to infer the types of the model fields for us.

We ran into a bug in production caused by two issues:
- Some users came from orgs that didn't have a website and since
the URL field was required, they submitted invalid URLs.
- We didn't properly respond to invalid form submissions, which
led to UnboundLocalError exceptions in another part of the
code.
This commit solves this by doing the following:
- We now allow blank URLs and have a convenient placeholder text
label that tells users that they may leave the URL field blank.
- This commit refactors the code such that invalid form submissions
result in an informative error message about what exactly went
wrong.
We are starting to run into situations where this data could be
quite useful for making future decisions, so it makes to store it
in the database, not just in an email.
This also fixes a bug in void_all_open_invoices function. If a realm
with a local Customer object but without an associated stripe.Customer
is passed to void_all_open_invoices, then the function will end up
voiding the last 10 invoices created by billing system instead of voiding
no invoices at all. This is because stripe.Invoice.list(customer=None)
return last 10 invoices across all customers.
But this bug won't cauuse any issue in production since
void_all_open_invoices can be only invoked from /support page. And we
show the option to void invoices in support page only if the realm
has a paid plan. And it's not really possible for a realm to have
a paid plan without having an associated stripe_customer_id. Plus I
went through the void events in stripe stream since the PR to add
void invoices was merged and there does not seems to be any suspicious
events.
Fixes#2665.
Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

Only CustomerPlan.ACTIVE is being used in the code / in production, so don't
need a db migration to move the other CustomerPlan.status constants around.
This is a major rewrite of the billing system. It moves subscription
information off of stripe Subscriptions and into a local CustomerPlan
table.
To keep this manageable, it leaves several things unimplemented
(downgrading, etc), and a variety of other TODOs in the code. There are also
some known regressions, e.g. error-handling on /upgrade is broken.
A lot of the seemingly unrelated test fixture changes are because we're
removing a query to stripe in the upgrade path, in cases when the user's
realm has an existing Customer object.
