feat(core): Add command to trigger license refresh on workers (#7184)

This PR implements the updated license SDK so that worker and webhook
instances do not auto-renew licenses any more.

Instead, they receive a `reloadLicense` command via the Redis client
that will fetch the updated license after it was saved on the main
instance

This also contains some refactoring with moving redis sub and pub
clients into the event bus directly, to prevent cyclic dependency
issues.
