Resolve API route dependencies on the event loop FastAPI runs a plain `def` dependency in its thread pool on every request. The server's API routes depend on several such functions, mostly `provide_database_interface`, so nearly every request handed CPU-only work to a worker thread and back. Routes now depend on `aprovide_database_interface`, an async wrapper that keeps `provide_database_interface` available to its synchronous callers, and on `provide_worker_lookups` instead of the `WorkerLookups` class. The remaining dependencies become `async def`; none has a synchronous caller. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Stop the async flow engine from blocking its event loop on the suspension observer The suspension observer of a deployment flow run runs on its own thread and event loop, but the async engine waited for it on the calling thread: it blocked until the observer was ready when the run started, and joined the observer thread (up to 2 s, with the observer polling for stop every 0.2 s) when the run ended. When several flow runs share one event loop, each start and end stalled all of them. The async engine now awaits the observer's readiness and shutdown through futures that the observer thread resolves on the engine's loop. The observer stays on its own thread so it keeps receiving suspension events while flow code blocks the flow's thread, and it now wakes as soon as it is asked to stop instead of within 0.2 s.
