refactor: remove makeRuntime from TuiConfig, use AppRuntime

Add TuiConfig.defaultLayer to AppLayer so TuiConfig.Service is available
via the shared runtime. Replace the local makeRuntime with dynamic
import of AppRuntime in the facade functions to avoid circular deps.

Keeps facade functions (get, waitForDependencies) intact since they are
spied on by test/fixture/tui-runtime.ts mockTuiRuntime helper.
