Add jump ahead buttons for task workflow

Enable users to skip intermediate task states in the expanded view. Users can now directly mark tasks as in-progress or complete without going through all workflow steps.

Changes:
- Add "Mark In Progress" button for unclaimed tasks (skips claiming)
- Add "Mark Complete" button for unclaimed and claimed tasks (skips intermediate states)
- Maintain existing workflow buttons (Claim Task, Start Task, Unclaim)
- Use concise, industry-standard button labels following common task management UX

Button layout:
- Unclaimed: "Claim Task" (default), "Mark In Progress" (outline), "Mark Complete" (outline)
- Claimed: "Start Task" (default), "Mark Complete" (outline), "Unclaim" (outline)
- In Progress: "Mark Complete" (default), "Unclaim" (outline)
- Completed: "Unclaim" (outline)

This provides maximum flexibility for different task management workflows while maintaining clear visual hierarchy with primary/outline button variants.
