## Summary by CodeRabbit


- **New Features**
- Enhanced internationalization support across various components by
utilizing the `i18n` object for date formatting.
- Streamlined locale management by removing cookie-based language
handling and adopting a more centralized approach.

- **Bug Fixes**
- Improved date formatting consistency by replacing the `LocaleDate`
component with direct calls to `i18n.date()` in multiple components.

- **Documentation**
- Updated localization strings in the `web.po` files to reflect recent
changes in the source code structure.

- **Chores**
- Minor formatting adjustments and code organization improvements across
various files to enhance readability and maintainability.
