feat(task-list): add tooltips for task indicators and enhance localization

- Introduced tooltips for subtasks, comments, attachments, subscribers, dependencies, and recurring tasks across various components to improve user experience.
- Enhanced localization by adding new translation keys for these indicators in multiple languages, ensuring consistent messaging for users.
- Updated components such as TaskRow, KanbanTaskCard, and EnhancedKanbanTaskCard to utilize the new tooltip functionality, improving clarity and accessibility.
