feat: redesign site as a modern developer portfolio

- New home page: hero, stats, about, focus areas, stack, projects, contact
- Light/dark theme with system default and persisted toggle
- Content centralised in data/profile.js
- Restyle /rates to match; remove it from nav and projects
- Afriex: log a clear error now that its API requires a device id
