Add Explore/Quote dual mode to catalog page

- Add CatalogMode type (explore/quote) to useCatalogSearch
- Create ExplorePanel component with view toggle (offers/hubs/suppliers)
- Create QuoteForm and QuotePanel components for search form
- Refactor CatalogPage to fullscreen map with overlay panel
- Simplify catalog/index.vue to use new components
- Add translations for modes and quote form (ru/en)

The catalog now has two modes:
- Explore: Browse map with offers/hubs/suppliers toggle
- Quote: Search form with product/hub/qty filters to find offers
