feat(10-01): update handleDragEnd and renderFields for typed field creation

- handleDragEnd: determine droppedType from active.id with validTypes set guard
- handleDragEnd: checkbox fields drop at 24x24pt; all other types drop at 144x36pt
- handleDragEnd: newField now includes type property set to droppedType
- renderFields: use getFieldType() + PALETTE_TOKENS lookup to get per-field color and label
- renderFields: border, background, and text color are now driven by fieldColor
- renderFields: resize handle corners use fieldColor instead of hardcoded blue
- renderFields: span displays fieldLabel instead of hardcoded 'Signature'
