/** v2.2.0 — intensive E2E for the history-edit feature.
 *
 * The user (Discussion #49 follow-up) explicitly asked: "das müsste intensiv
 * getestet werden ob die Änderungen korrekt gespeichert werden". This script
 * exercises the full roundtrip via the live HA WebSocket:
 *
 *   1. find an existing maintenance object + completed task with ≥1 history entry
 *   2. record the original entry payload
 *   3. send maintenance_supporter/task/history/update with patched fields
 *   4. fetch the object again, verify the patch landed
 *   5. test edge cases: clear notes (None), edit timestamp updates last_performed
 *   6. read back AGAIN after a brief wait — confirms persistence isn't lost
 *
 * No browser UI needed — this is pure WS roundtrip, the most reliable layer.
