- Validate GSTIN shape, state code and checksum
isValidGstNumber accepted any 15-character string, so a pincode (110095, rejected only for
length) and junk (Hdjiekwbdbsjskz) reached fofo_store.gst_number, which billing sends to NIC
as the recipient - the invoice is then refused and the goods cannot ship.
Now: 2-digit state code + PAN + entity + Z + mod-36 check digit, trimmed and upper-cased.
Blank still passes (the field is optional); callers needing one present check that themselves.
Checked against live data: 1,569 of 1,570 well-formed partner GSTINs pass, the one that fails
(HRSP330) has a genuinely wrong check digit.
Adds RTLR_1020 / RTLR_1021 for the invalid and mismatched cases.
