deal with timeouts because sending mail takes too long in production

[Jumpy-Squirrel]

We are seeing timeouts in production in two situations:

• While performing status changes. Here the solution is probably to increase the (currently rather small) timeout for the endpoint.
• While receiving the payments-changed webhook. Here we cannot increase the endpoint timeout further because our payment provider that originally sends the request that causes this webhook has a hard timeout of 10 seconds. Solution is probably to send this email asynchronously.
  • Note that for other processing, async sending of emails has some undesirable downsides. We WANT the admin to see an error if a "you have been cancelled" mail cannot be sent.
