Alexander c73363e93d fix(shopping/loyalty): emit FNC1 codewords for Supercard
Coop Supercard uses GS1 Data Matrix — the payload contains FNC1
separators between fields, not literal 0x1D bytes. Enable bwip-js
parsefnc so ^FNC1 placeholders in the env value produce genuine
FNC1 codewords (codeword 232), matching the physical card and
letting checkout scanners parse the GS1 element string.

Alexander 0ab98690eb feat(shopping): loyalty-card modal with build-time barcodes
Adds a CreditCard button on the shopping list that opens a modal
showing the user's Coop Supercard (Data Matrix) and Migros Cumulus
(Code 128). Card numbers come from SHOPPING_COOP_SUPERCARD_NUMBER
and SHOPPING_MIGROS_CUMULUS_NUMBER env vars; a prebuild script
renders each to an SVG (~1-2 kB) in static/shopping/ so no barcode
library ships to the client. Cards missing their env var are
silently skipped, and the generated SVGs are gitignored to keep
personal numbers out of the repo.
