  Add HdfcProcessingHelper: per-payment REQUIRES_NEW wrapper for HDFC credit writes
  
  Isolates the hdfc_payment insert + wallet-credit / sidbi-sanction writes in
  their own transaction so concurrent duplicate webhooks (HDFC retry, manual
  entry, reconciliation) can't poison the caller's session. On the deadlock/
  duplicate-key path (DataIntegrityViolationException), logs once at INFO and
  returns silently — the row's side-effects are owned by whichever path
  inserted it first; re-applying would double-credit.
  
  Mirrors the OfferProcessingHelper pattern (also REQUIRES_NEW per item),
  keeping the controller's outer transaction clean and making this method
  safe to invoke from a batch loop later without refactor.
