Improve Linear sub-issue import behaviour

When importing issues from Linear, parent issues and sub-issues are currently shown as a flat list with no visible hierarchy. This makes it hard to understand which issues belong together and adds friction when trying to mirror a Linear issue structure inside Locu

What would help

• Show sub-issues nested or indented beneath their parent issue during import

• Allow importing all sub-issues automatically when a parent issue is imported

Too Much Friction
Right now, importing a parent issue with its related sub-issues is more manual than it should be. The current workflow (for me) feels too fragmented:

• Find each issue separately in the list

• Import issues one by one

• Manually reorganise them afterward in Locu
