Nan Gao 926406e0d6 fix(channels): make runtime provider state authoritative (#3580)
* fix(channels): make runtime provider state authoritative

* make format

* fix(channels): close runtime provider config races and status gaps

Address review findings on the runtime-provider-state change:

- configure/disconnect now re-read the live app.state.channels_config
  after the worker await and mutate only the affected provider key in
  place, so a concurrent mutation for a different provider is no longer
  clobbered by a stale pre-await snapshot.
- disconnect revokes DB connection rows before committing the store and
  cache, so a repo failure cannot leave the store/cache "disconnected"
  while the DB keeps "connected" rows a later re-configure would
  silently reactivate.
- _provider_response preserves non-connected statuses (e.g. revoked)
  when the provider is unavailable, only masking a stale "connected"
  row as not_connected.
