webhooks.py: we'll get this right eventually

webhooks.py: fetch submitter from payload

webhooks.py: additional todo edge cases

webhooks.py: handle emailed tickets without name

webhooks.py: fix todo events via email

services.py: fix variable name

services.py: correct GQL variable name for CreateTool

and will be handled in a follow-up patch.

Upgrade to Alpine 3.20

services.py: further GraphQL refactoring

git.sr.ht usage to be routed through GraphQL, save webhooks which will

services.py: use GQL to fetch git repos

services.py: fetch *.yaml manifests for patch builds

.builds/alpine.yml: use upgrade -Ua

Upgrade to Alpine 3.19

These origins are only ever used to access the REST APIs and need to be
resolvable internally.
