fix(a11y): wire aria-controls + aria-expanded on GLP-1 dose-history details

The native <details>/<summary> element conveys state via the open
attribute, but the rest of the app's accordions also surface
aria-controls + aria-expanded so SR users hear the same contract on
both. The disclosure now references the inner panel by ID and the
expanded state mirrors the React-side toggle. Closes W10 design L3.
