Canonicalize legacy socket pairs and tagged tuples before storing
or comparing `Registry.addrs`, keeping existing config readable
when tractor emits protocol-tagged forms.
Also,
- broaden registry/runtime addr annotations for both wire shapes
- compare service fixture addrs through tractor's address codec
- use tractor's shared `--ll` pytest option instead of
registering it twice
- cover mixed legacy/tagged registry state and `pikerd` startup
