feat(combos): add new routing strategies and i18n support

- Add new routing strategies: fill-first, auto, lkgp, and context-optimized
- Add comprehensive strategy guidance and help text for new routing modes
- Implement i18n support for mode pack labels in intelligent routing step
- Update English and Chinese translations for new combo builder features
- Extend strategy recommendations with new routing mode examples

This enhances the combo builder with more sophisticated routing options
and improves internationalization coverage.
