get_event_loop() is deprecated on Python 3.11+ when there is no running
loop and is slated to change behaviour further.
- SSEManager.setup() ran at import time (app.api.utils) via
get_event_loop(); this only worked because uvicorn imports the app
inside its loop and would break when imported without a running loop
(e.g. a Celery worker). Start the broadcast consumer lazily from
within a running loop instead.
- everywhere else the pattern was get_event_loop().create_task(x)
inside a coroutine; replace with asyncio.create_task(x).

This is a feature that allows to fetch the app status via a celery
task which stores the result in the Redis database and notifies the API
of the change. The API sends a notification to connected clients via the
SSE mechanism.
Using a background task allows to avoid crashing the whole API if the
script call fails.
The by default the cache is refreshed every 30 minutes. This can be
changed by setting the `BAPI_APP_STATUS_UPDATE_INTERVAL_MIN` environment
variable.

Some apps might give status information that is computationally to
expensive to include in the normal status endpoint which can be polled
more often.
