/// Модальный интерфейс для создания или редактирования существующей заметки.
///
/// Особенности:
/// - **Инициализация**: Умеет подтягивать данные из [existingNote] для режима редактирования.
/// - **ID Generation**: Использует пакет [Uuid] для генерации уникальных идентификаторов
///   при создании новых записей.
/// - **Keyboard Handling**: Управляет отступами через [viewInsets.bottom] и
///   принудительно закрывает клавиатуру через [FocusScope] при отмене.
/// - **Data Integrity**: Гарантирует наличие текста перед активацией процесса сохранения.
