feat(doubao): implement challenge handling and monitoring improvements

- Added classification for `doubao_challenge_required` as a challenge in platform-auth-adapters.
- Enhanced account action summaries to include specific messages for Doubao human verification.
- Introduced monitoring functions to filter out blocked platforms based on account health.
- Updated task leasing to support platform-specific filtering for monitor tasks.
- Refined issue aggregation in HomeView to consolidate Doubao challenge failures into a single actionable item.
- Improved backend logic to handle platform IDs in task leasing requests and responses.
- Added tests for new functionality, ensuring proper handling of Doubao challenges and task leasing logic.
