Port `.cli` & `.service` to latest `tractor` registry APIs

Namely changes for the `registry_addrs: list`, enable_transports: list`
and related `tractor._addr` primitive requirements.

Other updates include,
- passing `maybe_enable_greenback=True`,
- additional exc logging around `pikerd` syncing/booting,
- changing to newer `Context.wait_for_result()`,
- dropping (unnecessary?) `maybe_open_crash_handler()` around `pikerd` ep.
