fix(#678): distinguish CoreScope not-found from unreachable (#571)

CoreScopeService.fetchCounts returns a three-state CoreScopeResult { found | notFound | unreachable } instead of a nullable count. Reachable-but-empty -> notFound ('Not seen by CoreScope yet'); network/HTTP/parse error -> unreachable. Channel-chat tap-refresh banner switches on status; adaptive poll reads .counts.

Epic #677. Closes #571.
