FIx some bugs

[daunera]

This PR focuses on improving localization, data validation, and repository consistency. It addresses issues with record creation in the fuel and insurance modules and ensures the calendar behaves correctly across different locales.

Localization and UI

• Hungarian Support: Added missing Hungarian translations.
• Calendar Locale: Updated the calendar component to handle locale-specific settings, such as the starting day of the week.
• Date Validation: Fixed the validation check for date format inputs within the settings menu.

Data Integrity

• Record Creation: Resolved an issue where fuel logs, insurance, and pollution certificate records were being saved with a null ID key. The logic now filters out the ID key during the creation process.

Maintenance

• Git Configuration: Added a .gitattributes file to enforce LF line endings across the project.

Closes #195

@javedh-dev I am not familiar with migration, so I could not do it, if someone already had a fuel log, insurance, pollution cert record with null id, than for those record generate uuid id with a migration file
