When no backend is configured (empty registry / NO_BACKEND sentinel),
loadAgentServerInfo() was returning null without throwing, causing
OptionService.getConfig() to succeed silently. root.tsx then rendered
the home page instead of the MissingAgentServerScreen with the manage
backends modal.
Now loadAgentServerInfo() checks for the NO_BACKEND sentinel when
getEffectiveLocalBackend() returns null and throws
AgentServerUnavailableError, which root.tsx already handles by showing
the manage backends modal. The cloud-backend path (also null from
getEffectiveLocalBackend) is preserved — it still returns null.
