feat(providers): add timestamp-based sorting for provider list

- Add createdAt timestamp field to Provider interface
- Implement sorting logic: old providers without timestamp first, then by creation time
- Providers without timestamps are sorted alphabetically by name
- New providers are automatically timestamped on creation
