B2Action_SelectErrandObject

• Description
  * ===============
  * Opens the errand object picker so the player can ask the target character to fetch something.
  * Collects the carriable objects the target could pick up right now in its own site, sends them to BlueClient and
  * finishes immediately, so the conversation ends the moment the popup appears and the player is never locked into a wait.
  * The action does not queue anything on the target and does not pause the game: BlueClient owns the pause while the
  * popup lives, and B2PacketReceiver_UI::C_SelectErrandObject starts the errand Coop once the player confirms.
  * Because nothing is kept alive here, a save taken while the popup is open has no action state to restore.
  * Only the possessed character may hand out an errand, and only through a user-triggered play reason - autonomy and
  * SmartZoi are rejected so the picker can never open without a player asking for it.
  * The pick-up bag and the Coop id are not consumed here; they are forwarded to the popup and come back with the choice,
  * so both stay data-driven instead of hardcoded in the receiver.
  * ===============
  * Param:
  * S1: Pick-up InteractionBag used to gate the candidates, also reused when the choice is re-validated (PickUp)
  * S2: Coop played from the moment the player confirms until the object reaches the requester (Coop_Errand_HandOver).
  * It must be driven with CoopType HandOver, because the chosen object is carried into the scheduler as its
  * hand-over object and the fetch task resolves it back through the CoopHandOverObject target filter
  * F1: Search range around the runner in unreal units. 0 covers the whole site
  * F2: -
  * Note:
  * OnInit(): Reads the pick-up bag from Action.S1, the errand Coop from Action.S2 and the search range from Action.F1.
  * OnPlay(): Rejects anything but a user-triggered request from the possessed character, collects the candidates through
  * B2ErrandHelper, finishes without opening anything when there is nothing to fetch, then sends
  * S_OpenErrandObjectPicker and finishes right away.
