Refactor Localization System in pactus-gui to Match pactus-gui-widgetbook

[esmaeil-ahmadipour]

Overview

The pactus-gui localization system relies on Easy Localization , which has buggy behavior when changing languages. We need to replace it with the l10n package to align with pactus-gui-widgetbook for consistency, better maintainability, and a centralized translation key structure.

Goals

• Replace Easy Localization with l10n.
• Centralize and standardize translation keys.
• Align with pactus-gui-widgetbook.

Proposed Changes

1. Replace Easy Localization with l10n, removing outdated dependencies and configurations.
2. Centralize translation keys in one file with a consistent naming convention.
3. Refactor translation logic to align with the new system and update all relevant code.
4. Ensure compatibility with pactus-gui-widgetbook.
5. Update tests to validate the new system and ensure that the CI pipeline includes checks for correct translation automation, ensuring no missing translations.

Impact

• Existing code dependent on Easy Localization will need updates.
