This commit removes the code the puts areas into the session and instead
creates and then updates a draft broadcast in the database.
This is so we can avoid session-related bugs, and potentially having a
large session when we start adding personalisation etc.
Once a broadcast is ready to go it is set to `broadcasting` straight
away with no approval. We’ll revisit this as we learn more about how
users might want to manage who can create and approve broadcasts.
The tests are a bit light in terms of checking what’s on the page, but
clicking through the pages is probably good enough for now.
These are just so we have some pages to click through for now. They
don’t use real templates, or any of the broadcast stuff from the
database.
But I think it’s useful to get some skeleton pages in first so that we
can see the map etc working in production, then build on that, without
having to do it all in one mega PR.
For that reason there are two short term things I’ve done in this commit
which should be revisited soon:
- no tests for the endpoints
- data about which areas are selected is stored in the session
