The topology flip: all data-feed consumers now route to the
new `datad.<broker>` sibling daemon; `brokerd` becomes
trading-only and is ONLY ever booted lazily by `emsd`'s
`open_brokerd_dialog()` (see prior commit). Chart-only and
paper sessions run with zero (live, credentialed) `brokerd`
procs B)
Deats,
- `open_feed()` -> `maybe_spawn_datad()` (NB: imported
relative-direct from `._daemon` to dodge a partial-init
cycle via `piker.service`); flip the `open_feed_bus()`
actor-name assert to `'datad'`; comment sweep.
- slim `_setup_persistent_brokerd()` to a trading-only
fixture: console logging + pinned-open ctx; the feed-bus
alloc moves to `_setup_persistent_datad()` and backend
`open_trade_dialog()` ctxs own their own task trees.
(the `piker ledger` ad-hoc actor enters this same slimmed
fixture - exactly what it needs.)
- repoint data-flavoured spawn sites to `maybe_spawn_datad`:
`.ui._app` symbol-search (+ rename
`install_brokerd_search` -> `install_datad_search`),
`.brokers.core.symbol_search()`, `.brokers.cli`
`brokercheck`/`record`, legacy kivy `.ui.cli` +
`option_chain`'s `wait_for_actor()`.
- invert `tests.test_services` expectations: feed/EMS-paper
flows must spawn `datad.kraken` and `paperboi.kraken`
with an explicit negative assert that NO `brokerd.kraken`
service task exists.
