feat(router): permit log service name to be configured via env var

[brokenpip3]

This PR will make the "service" value in router logs configurable through an env var, while keeping the current hardcoded @wundergraph/router as the default.
I was not able to find any existing test for router/cmd/main.go, in case you prefer I can add a couple of test cases to cover this change.

Instead off having this as a flag, it would be more useful to support it in the config file. For this, you need to update

cosmo/router/pkg/config/config.go

Line 1006 in d6a443e

type Config struct {

There you can also enforce the default, make it available as ENV + make it required.
