Summary

• Cursor now follows the same resource by ID (or Name for keypairs) instead of staying at the same row index when lists auto-refresh, re-sort, or items are added/removed
• Fixes disorienting cursor jumps during navigation when tick-refresh causes re-sorting, and when returning from detail views after deletion
• Applied consistently across all 9 list views: serverlist, volumelist, routerlist, lblist, imagelist, keypairlist, floatingiplist, networklist, secgroupview

Test plan

• Select a resource in any list, wait for auto-refresh tick, verify cursor stays on the same resource
• Change sort column/direction, verify cursor follows the resource
• Delete a resource from a detail view, verify cursor stays at a valid position
• Filter the server list while cursor is on a resource, verify cursor tracks correctly
