Reassign several deals

Hands up to 200 trattative to another colleague in one call — the grid’s own bulk action, for somebody who has left or a territory that has changed. Owner reassignment is the ONLY thing it does: it cannot move stages, because a lost deal needs its own reason and one card already sitting in the destination would fail the whole batch, so move stages one at a time with crm_advance_deal. Won and lost deals change hands too: the owner is not one of the figures a closed deal keeps. Ids you can no longer see simply do not change, and the answer reports how many actually did. It does not reset anybody’s idle clock: redistributing a leaver’s pipeline is not contact with those customers.
