Prep for the `brokerd` -> (`datad` + `brokerd`) actor split
by having each (split-style) backend declare which of its
submods host which daemon-kind's eps, exactly per the
`piker.data.validate._eps` groupings; `ib` already had
`_brokerd_mods`/`_datad_mods` so extend the convention to
`kraken`, `binance` and `deribit` (and add `'api'` to ib's
datad set since both kinds need the `Client` layer).
`__enable_modules__` stays as the (deduped) union so this
is a ZERO behavior change; flat backends (`kucoin` etc.)
just don't declare the split yet.
Also,
- add `validate.get_eps()` returning a backend's defined
eps per daemon-kind for spawn-time introspection.
- import `NoBsWs`/`open_autorecon_ws` from
`piker.data._web_bs` directly in `.kraken.broker` (they
were only re-exported via `.kraken.feed`) so the trading
mod doesn't depend on the feed mod for ws primitives.
