feat(clearing): add CTS/NACH clearing UI with real NPCI batch sessions

- CTS clearing module: inward batches (validate/pass/return), outward presentment
  capture, positive pay, settlement, reconciliation
- Outward Clearing merged into one screen: Pending Cheques + Batches tabs (a real
  clearing session per NPCI submission, either the 2-hourly job or manual send),
  drill into a batch to settle/dishonour its cheques
- Date-range, text, and quick (Today/Yesterday/All) filters with pagination across
  inward batches, outward presentments, outward batches, and batch detail
- NACH clearing module (mandates, batches, transaction decisioning)
- Shell/sidenav wiring for both new modules
