feat: Implement active workout flow with status management

- Added `status`, `total_sets`, and `total_volume` fields to the Workout model.
- Introduced `source_kind`, `title_snapshot`, and `image_s3_url_snapshot` fields to the WorkoutItem model.
- Created endpoints for managing active workouts, including finishing and discarding workouts.
- Updated workout creation to ensure only one active workout exists per user.
- Implemented batch addition of workout sets and updates to workout set details.
- Enhanced database schema with Alembic migrations to support new fields and constraints.
- Added validation to ensure at least one field is provided for workout set updates.
- Updated calorie estimation logic to reflect new workout set structure.
