Add test runner dashboard service (test.rose-ash.com)

Public Quart microservice that runs pytest against shared/tests/ and
shared/sexp/tests/, serving an HTMX-powered sexp-rendered dashboard
with pass/fail/running status, auto-refresh polling, and re-run button.
No database — results stored in memory.
