Implement localization for Widget Extension

[bbdyno]

Description

Currently, the Main App and Widget Extension need to share localized strings to ensure a consistent user experience. Duplicating Localizable.strings files across targets leads to maintenance issues and potential inconsistencies.

We need to extract localization resources into a separate Shared Framework (or Swift Package) so that both the Main App and the Widget Extension can reference a single source of truth.

Goal

• Create a dedicated module (e.g., DMateResource) for localized resources.
• Ensure both the Main App and Widget Extension targets import and use this shared module.
• Eliminate duplicate string files in the project.
