feat(tests): introduce ROUTE_CALLS_KEY for organizing route calls

Addressed the aiohttp warnings by aligning the test scaffolding with current best practices. Added an AppKey constant and stored the route tracking list through it to satisfy aiohttp’s NotAppKeyWarning expectations. Swapped the websocket lambdas for async no-op handlers so the registered routes now point to coroutine callables, clearing the deprecation warning about bare functions.
