feat(insights): add <SuggestedPrompts> chip-strip component

New `src/components/insights/suggested-prompts.tsx` renders the
"Try asking" chip row from the v1.4.20 Insights redesign hero strip.
Five default prompts (whyMonday, weightVsPulse, weekVsMonth,
tellMyDoctor, medicationWorking) read from
`insights.suggestedPrompts.*`, click invokes `onPick` with the
localised string so the parent can route to the future Coach drawer.

Mobile-first: chips wrap to multiple rows on narrow viewports.
Dracula purple chip styling matches the existing card vocabulary.
Custom prompts array accepted for tests + future per-user sets.

EN + DE translation keys added in lockstep — i18n-locale-integrity
test stays green. Test suite: +9 specs covering default rendering,
locale switching, custom prompts, and chip-slot pinning.
