Cyrus GrayandGitHub 320e31f4b3 feat(upsell): add usage-aware banners, rate-limit modal, and shared usage hook (#403) (#440) ...

Phase 1 of the upsell flow for free users:
- Shared `useUsageState` hook with module-level cache (60s TTL)
- Reusable `UpsellBanner` component (info/warning/upgrade variants)
- `UsageLimitModal` shown when user tries to send at hard limit
- `GlobalUpsellBanner` for app-level usage warnings
- Pre-limit warning banner in Conversations at 80%+ usage
- localStorage-based dismiss persistence with cooldown

Closes #403
