content(website): reflect latest features across all pages

Full pass over the marketing site so every page reflects the current product:

- Features page: +"Works Offline" and +"Get Discovered on Koja" cards (NEW badges);
  rewrote "Real-time Notifications" to describe the dashboard sound+toast alert.
- Solutions: added offline / Koja / real-time-alert bullets across cafés,
  restaurants, chains, and cloud kitchens.
- Tour: POS step now mentions offline + auto-sync; kitchen step describes the
  sound+toast new-order alert on any screen.
- Docs: +Offline Mode and +Koja Discovery module guides (fa/en).
- appPromo: waiter-app "new order" alert notes sound.
- privacy/terms: "Last updated" June 2025 → June 2026.

Website build clean.
