fix(retry): pre-populate price list before re-importing failed orders

Production VENDING orders #485841978 and #485841895 (2026-04-28) crashed
on Retry with PL/SQL COM-001 because the retry path skipped the
CRM_POLITICI_PRET_ART pre-population step that bulk sync runs.

The price-list auto-insert (PRET=0) for missing CODMATs was only invoked
in sync_service.run_sync (lines 592-718). retry_service called
import_single_order directly, hitting pack_comenzi.adauga_articol_comanda
NO_DATA_FOUND on every CODMAT without a price entry.

Extracted the validation block into validation_service.pre_validate_order_prices
and call it from both bulk sync and retry. Single source of truth for
SKU validation, dual-policy routing (cont 341/345 → productie),
ARTICOLE_TERTI mapping resolution, and kit component price gating.

Tests: 3 unit + 3 oracle integration covering the regression scenario,
empty input, dual-policy routing, idempotency, and pre-validation
exception propagation.
