Paul Lorenz 667436b3b6 Stop the controller panicking on a tunnel v2 dial to an unknown service. Fixes #4442 ...

- uses the nil-safe getApiSessionId() in loadServiceForName, matching loadServiceForId; the v2
  tunnel circuit handler never establishes an api session, so the lookup-failure branch
  dereferenced a nil apiSession and took the controller down on any unresolvable service name
- makes the default admin check log a read failure and return instead of panicking; the check is
  advisory and runs in a goroutine that can observe a datastore the shutdown path has closed,
  turning a controlled exit into exit 2
- adds godoc for checkEdgeInitialized covering the advisory contract and the remaining fatal case
- notes both in the changelog
