IMS: accept, reject, pending — without portal clicking

IMS is mandatory since April 2026. Milaan turns your reconciliation into IMS decisions:

1. Run reconciliation, open the IMS tab and press Suggest from recon — matched → Accept, unknown-in-books → Reject/Pending, disputes → Pending.
2. Review with keys 1/2/3 (Accept/Reject/Pending). Add remarks where needed.
3. Export portal JSON and upload it via the GSTN offline tool.
4. After the 14th, press Recompute GSTR-2B on the portal.

⚠ Rejecting a credit note increases the supplier's liability — Milaan warns you inline.
