Await async assert_signal calls and match emitted payload args with any()
where tests only care that the signal fired, preventing orphaned 2s timeouts
that surfaced as false failures in later suites (e.g. hotbar_loadout_client_test).
Split HTTP verification reads into Assert in C# API and integration tests.
Add # Arrange/# Act/# Assert to GdUnit suites and keep Act free of assertions
where casts and busy guards are under test.
