/**
 * Moving mail across the own-account / shared-folder boundary, in both
 * directions, and between two shared folders (same owner and across owners).
 * The move is driven from the list context menu's "Move to" submenu; the
 * authoritative check is the server-side mailbox the message ends up in.
 *
 * Each cross-account case asserts delivery *and* that the read state survives
 * (Email/copy drops keywords unless carried). Removing the source, however, is
 * currently blocked by a Stalwart bug — onSuccessDestroyOriginal destroys the
 * copy's create-id instead of the source id, so the original is left behind
 * (support.stalw.art #1150). Those source-removal checks are pinned test.fail
 * until Stalwart ships the fix; same-account moves (Email/set) are unaffected.
