feat(task-phases): enhance phase creation with custom naming and localization updates

- Updated the phase creation logic to allow custom names, defaulting to a generated name if none is provided.
- Modified localization files for multiple languages to improve phase-related text consistency and clarity.
- Enhanced the UI components to reflect the new phase naming functionality and ensure proper integration with the task management system.
- Added dark mode styling for confirmation modals to improve user experience across themes.
