- _default_mcp_server_url() replaces the hardcoded localhost:8000 fallback,
deriving the port from settings.port so a custom PORT is honoured and all
fallback sites share one source of truth (removes the footgun where
settings.port looked wired but the OAuth-audience fallback ignored it).
- Clear _readiness_cache.statuses at loop start so dependency entries from a
prior lifespan run in the same process (integration matrix) don't linger as
stale, confusing checks output.
