Evolution API v5.5.2

Queue delivery-state correctness\n\n- Queued acceptance now explicitly reports messageWasSent=false, deliveryStatus=PENDING, and final=false.\n- Every actual delivery attempt resolves the current settings template and rechecks all safety rules.\n- Temporary policy blocks are requeued only inside the configured queue horizon.\n- Long waits and permanent policy changes mark the queue item FAILED with diagnostics instead of implying delivery.\n- OpenAPI and lifecycle documentation are updated.\n\nCloses #37.
