v1.4.34.3 — remove the dashboard Coach CTA

Per maintainer directive — the v1.4.34 IW-B "Frag den Coach" sparkles
button sat next to the "Hinzufügen" dropdown on the dashboard hero
and read as visual noise rather than a useful surface. Remove it; the
Coach drawer remains reachable from the /insights tree (its original
home), and the auth-shell `<CoachLaunchProvider>` + drawer mount stay
intact so any future page that wants its own opt-in CTA can call
`askCoach()` without churn.

The hook usages this leaves orphaned in `src/app/page.tsx`:
  - `useCoachLaunch` (only consumer was the CTA)
  - `useFeatureFlags` (only gate was `featureFlags.coach`)
  - `Sparkles` icon import

All drop out cleanly.

First release that lets v1.4.34.2's `pull_policy: always` show its
worth — the deploy mechanic should pick up the new image without a
manual host-side retag fallback.
