Enhance task progress calculation and UI handling

- Updated task progress calculation logic to incorporate weights and time-based estimations for subtasks.
- Improved SQL migrations to support new progress calculation methods and ensure accurate parent task updates.
- Enhanced frontend components to conditionally display progress inputs based on task type and project settings.
- Implemented socket events for real-time updates on subtask counts and progress changes, ensuring consistent UI behavior.
- Added logging for progress updates and task state changes to improve debugging and user experience.
