fix(workers): prevent uvloop from setting global event loop policy in healthcheck uvicorn ≤0.35.0 with uvloop installed sets a global uvloop.EventLoopPolicy() when starting, which breaks subprocess spawning when a SelectorEventLoop is used (uvloop's policy doesn't implement get_child_watcher()). This adds loop="asyncio" to the healthcheck uvicorn config to prevent this, and updates settings access to use the new get_current_settings() pattern.
