  Fix noon price-drop lock storm + wallet-rollback divergence
  
  Per-drop transaction isolation for the noon price-drop reprocess, mirroring
  the offer batch pattern (OfferBatchService / OfferProcessingHelper):
  - PriceDropProcessingHelper: readOnly id fetch + REQUIRES_NEW per-drop
  reprocess (processPriceDrop) + markItemSuccess
  - PriceDropBatchService: no-@Transactional orchestrator - fetch ids,
  createBatch, per-drop loop with markItemFailed, finalizeBatch
  
  Previously the whole reprocess ran under ScheduledTasks' class-level
  @Transactional as one ~20-min transaction, holding user_wallet
  PESSIMISTIC_WRITE locks for the entire run and timing out live
  /addAmountToWallet, /create-order and /scanSerialized at noon
  (LockAcquisitionException).
  
  Also narrow the rollback catch in PriceDropServiceImpl from Exception to
  ProfitMandiBusinessException: lock/DB failures now propagate and roll back
  the drop's REQUIRES_NEW unit (stays APPROVED, retried next run) instead of
  being swallowed while the IMEI is marked REJECTED with the payout still in
  the partner's wallet.
