Drop the standalone GLP-1 dashboard tile and its data-fetch route.
The /api/dashboard/glp1 endpoint has no consumer outside the retired
tile (no native client reads it), so the route, the tile component,
its test, the e2e spec, the locale keys, the query-key entry and the
drift-guard assertion all retire together.
The medication detail page and its bidirectional contracts stay
untouched. An opt-in dashboard widget that surfaces the same level
chart will land later in this cycle, anchored on the existing
dashboard-layout toggle list.
