Multilingual Product Admin Interface

Create a simple product management admin interface for a Flask application that supports multiple languages (English and Spanish). The interface should allow users to view and manage products, with all UI elements properly translated based on the user's language preference.

Requirements

Build a Flask-Admin interface with the following features:

1. Product Model: A simple product model with the following fields:

   • name (text)
   • description (text)
   • price (decimal)
   • in_stock (boolean)
   • created_at (datetime)

2. Admin Interface: Create an admin view for the Product model with:

   • List view showing all product fields
   • Create and edit forms
   • Column labels that display in Spanish when the user's locale is 'es'
   • Form field labels that display in Spanish when the user's locale is 'es'

3. Language Support: The application should support:

   • English (default language)
   • Spanish (locale code 'es')
   • Translations for these UI elements: "Name", "Description", "Price", "In Stock", "Created At"

4. Test Implementation: Write tests to verify:

   • Column labels appear in Spanish when locale is set to 'es' @test
   • Form field labels appear in Spanish when locale is set to 'es' @test
   • Column labels appear in English when locale is set to 'en' (default) @test
