fix: replace hardcoded English strings with i18n translations

- Added translation keys for all error messages in message edit/delete operations
- Updated webviewMessageHandler.ts to use t() function for all error messages
- Added translations to all 17 supported languages for the new keys:
  - message.no_active_task_to_delete
  - message.invalid_timestamp_for_deletion
  - message.cannot_delete_missing_timestamp
  - message.cannot_delete_invalid_timestamp
  - message.message_not_found
  - message.error_deleting_message
  - message.error_editing_message

This addresses review feedback from mrubens about hardcoded English strings.
