copies the absolute path to the managed skills workspace to the clipboard
and shows a toast confirmation.
- Add sourcePath field to CompanySkillDetail and CompanySkillListItem types
- Return managedRoot path as sourcePath from deriveSkillSourceInfo for
Paperclip workspace skills
- Make source label a clickable button in SkillPane detail view
