[POS][Local Catalog] Connect product list to POS database

[samiuelson]

WOOMOB-1072

Description

The goal of this PR is to load products from the DB instead of the existing in-memory cache / remote call hybrid store. Currently, the logic that decides on which data source to use is based on the feature flag WOO_POS_LOCAL_CATALOG_M1 state.

⚠️ Known issue: WOOMOB-1370 - variations have wrong names. This will be solved in a separate PR.

Steps to reproduce

—

Testing information

1. Verify that in the release build (FF disabled), the previous data source implementation is used.
2. Verify that PTR works when FF is disabled.
3. When the FF is enabled, verify that products load correctly - full list. They should load significantly faster without pagination.

Pull Request Overview

This PR integrates local database storage for the POS product catalog, controlled by the WOO_POS_LOCAL_CATALOG_M1 feature flag. When enabled, products are loaded from the local database instead of the existing cache/remote hybrid approach.

• Adds sorting by product name (case-insensitive) at the database level
• Introduces a new database-backed data source for products with search filtering capabilities
• Updates product retrieval logic in cart and totals repositories to support both local catalog and legacy flows
