fix: Restore all missing features to Pie control panel

- Added back outer radius slider control with min/max constraints
- Added conditional inner radius control that only shows when Donut is checked
- Added color palette selector component
- Added conditional Label Line control that only shows when Show Labels is checked
- Fixed double headers on Metric and Group by controls by removing duplicate labels
- All controls now properly configured with renderTrigger where appropriate
