fix(gui): avoid asyncio.run() and cpu_bound for async health checks

Move SystemService.health_static() call from the sync inner function
_add_application_version_selection_section() to the outer async
_page_application_describe(), capturing the result via closure.

Also fix gui/_frame.py to await health_static() directly instead of
passing it to run.cpu_bound(), which ran the async function in a
subprocess with no event loop, causing "coroutine was never awaited".
