The hero rings read their owner from the surface map instead of their
own map, and the readiness, recovery and sleep score rings no longer
wait on the AI analysis switch: they are computed scores, not model
text. The dose ring still follows the medications module.
SURFACE_MODULE names each surface a toggleable module owns (nav entries,
Insights pages, overview blocks, trend slots, add-menu entries, dashboard
widgets and summaries, derived scores, Settings sections, correlation
channels) as <kind>:<id>. isSurfaceVisible answers from it on the server
and in the browser, useSurfaceVisible reads it against the account.
The insights key owns no surface: it means AI analysis, and the Insights
area is data.
