Since it usually means the data-provider backend is keying the msgs
incorrectly (not using the equivalent `MktPair.bs_fqme` which as
would be rendered from the delivered `FeedInit.mkt` instance..) and
reporting the subs list should make it clear how the fqme matching is
off.
Deats,
- use the new `.log.mk_repr()` for a formatter.
- add a commented info emission that can be unmasked to help debug any
such cases as mentioned in the summary ^^.
