fix(panel): resolve undefined font vars + remove dead client code

- layout.tsx/globals.css: font-sans/font-mono pointed at undefined --font-geist-*
  vars (Geist-starter leftover); now resolve to the actually-loaded Inter via
  --font-inter. No visible change.
- remove orphaned company-goals-card.tsx (unmounted; live charter UI is goals-tab.tsx)
- remove dead streamApi transcription REST client (zero consumers) + its barrel
  export; AgentStreamViewer (a different, live websocket-based component) untouched.
