PR Summary

This PR adds functionality to delete all download sources at once across multiple language files and components. Here's a focused summary of the key changes:

• Multiple language files have incorrect translations for 'removed_download_sources', using "fonts removed" instead of "download sources removed" (affecting bg, da, de, hu, id, kk, ko, ru, tr, zh)
• Added new ConfirmationModal prop buttonsIsDisabled to support disabling both confirm/cancel buttons during deletion
• Implemented deleteAllDowloadSources function in worker with a typo in the name and missing error handling
• Added CSS styling for a new "Remove All Sources" button positioned with flex-end justification
• Added bulk deletion UI flow in settings-download-sources.tsx with confirmation modal and state management

The implementation needs several fixes for translation accuracy and error handling robustness.
