fix: switch Oban to manual testing mode to eliminate spurious compile errors

The inline testing mode caused CompileWorker to run immediately on every
bundle creation, failing with "zentinel binary not found" since the CLI
isn't available in tests. Manual mode lets bundles stay in pending state
naturally, and tests that need compiled bundles use compiled_bundle_fixture.
