Refactor brand service and related components

- Removed ListQuestionVersions method and associated types from BrandService and Queries.
- Updated PromptRuleGenerationService to change task naming and handling.
- Enhanced ScheduleTaskService to support filtering by created date range and keyword.
- Introduced InstantTaskService for managing instant tasks with appropriate filtering and response structures.
- Added InstantTaskHandler for handling API requests related to instant tasks.
- Created InstantTaskTab component for the admin web interface to display and manage instant tasks.
- Updated database migrations to rename source types for articles and generation tasks.
- Adjusted models and repository queries to reflect the removal of question version handling.
