Move the complete refresh operation into a service.

This new call moves cache invalidation, but serverRefreshProviders still coordinates usage-limit refresh, snapshot refresh, and the per-instance refreshModels() loop. Expose one service operation for that sequence. Then have the RPC handler call it and map its errors.

As per coding guidelines, “A transport handler does three things: decode the request, call one service method, and map the service's typed errors to the transport's error. Nothing else.” As per path instructions, “Provider capabilities belong on the existing domain service.”

Review comment at @apps/server/src/ws.ts at line 2178:
Move the full provider refresh sequence from serverRefreshProviders into the
existing provider domain service, including cache invalidation, usage-limit
refresh, snapshot refresh, and the per-instance refreshModels loop. Expose one
service operation for this sequence, then have the RPC handler only decode the
request, call that operation, and map its typed errors to the transport error.
