fix(dashboard): paint the dose ring in the medication hue, not green

The 'Doses today' ring pinned the ring system's green arc — a colour
that vocabulary reserves for band semantics. Every medication surface
in Insights paints --primary (the compliance progress bars, the
compliance trend line, the drug-level and dose-strength curves), so the
ring now rides a new constant 'meds' hue on that token: flat by design
(both gradient stops on --primary), never a band gradient over pending
morning doses. Contrast, computed: dark #bd93f9 — 6.78:1 card / 5.90:1
bg; light #644ac9 — 6.00:1 card / 5.60:1 bg; both clear the 3:1
graphics floor with room. The guard now windows the assertion to the
dose ring's own SVG and pins primary present, ring-green absent.
