feat: redesign homepage with Radix UI and add dev environment defaults

- Replace title/tagline homepage with social profile design
- Add Radix UI Themes + icon libraries for modern UI components
- Provide sensible dev defaults for DB/secrets (no .env required)
- Add production safety checks for critical env vars
- Make optional features (cron, healthcheck) gracefully skip when unconfigured
