Queue via fly-to + Relocate; remove dedicated queue-add input (ISS-053, v0.32.0)

- LeftPane fly-to button enabled for any plane state; posts to /queue when the plane is flying, else /fly
- Relocate lists ALL planes (relocatable); relocate-go posts to /queue for a flying selected plane, else /fly
- Delete queue-add select + Add-to-queue button and shared queueAddDestIcao state; leg rows/cancel kept
- e2e/queue.spec.ts test 1 adds its queued leg via the Relocate section (starter is flying)
- e2e/two-planes.spec.ts per-plane-queues test adds the starter's second leg via API POST /queue
