Fix supplier info and catalog filtering bugs

1. Add latitude/longitude to GetSupplierProfile query
   - Without coordinates, supplier merge overwrites geo node data
   - Causes "Supplier has no coordinates" warning and no offers loading
   - Affects: useCatalogInfo.ts loadSupplierInfo() and useCatalogProducts.ts fetchProducts()

2. Add bounds validation in catalog composables
   - Validate bounds coordinates before passing to GraphQL or using in filters
   - Prevents 400 errors when bounds contain NaN/undefined/Infinity
   - Fixed in: useCatalogHubs.ts and useCatalogSuppliers.ts
