Add make_meta util and update products API

Introduce app.utils.make_meta to centralize creation of response metadata (severity, title, version, base_url, time). Replace duplicated inline meta dicts in app/api/products/products.py and app/api/products/update.py with calls to make_meta. Simplify the update endpoint to return a placeholder indicating CSV upload handling (previous CSV-processing logic was removed). Add tests/tests_make_meta.py to validate meta fields, default BASE_URL, and timestamp format. These changes DRY up metadata creation and make it easier to test and maintain.
