selectNode() resets fileItems=[] and activeTab='overview'. Setting
activeTab='files' programmatically does not trigger the tab click
handler that calls loadFolder(), so the file tree stays empty.
Fix: explicitly call await loadFolder(selectedNode.id) in the files
branch of openActivityTarget.
Also: unified resolveActivityTarget return shape to always use
targetId/targetPath regardless of targetType.
