BREAKING CHANGE: Remove all data analysis features
This commit removes all database-dependent functionality and simplifies
the application to focus on authentication and user management only.
Changes:
- Remove all /api/data and /api/metadata server endpoints
- Remove Supabase configuration from nuxt.config.ts and .env.example
- Remove @supabase/supabase-js dependency from package.json
- Delete data analysis pages: explorer, metadatos, rawExplorer, panorama,
comparativa-cosechas, informe-ingresos
- Simplify sidebar navigation to show only "Inicio"
- Update home page to focus on authentication and profile management
- Remove "Supabase" and "Solo lectura" badges from navbar
- Keep only auth-related API endpoints: /api/auth/status and /api/auth/check-group
The application now serves as an authentication-protected portal with:
- Authentik SSO integration
- User profile management
- Settings and notifications pages (coming soon)
- No database or data analysis features
- Add AuthSessionStatusButton to dashboard layout navbar
- Redesign button as compact icon button for navbar integration
- Button checks session status against Authentik in real-time
- Styled to match navbar aesthetic with hover effects
