Canteen Management

Kitchen section completion. Three slices, each API + portal page + tests.

1. Recipes and live costing

   • Recipe with ingredient BOM; cost per portion computed on read from
     current store-item rates, never stored.
   • A GRN that changes an ingredient's price changes recipe cost immediately.
   • /recipes page with BOM editor and detail dialog.

2. Wastage

   • Log waste against a recipe or a store item, with reason and cost value.
   • Store-item waste reduces stock through the ledger; recipe waste does not.
   • /production page with wastage log and stat cards.
   • Issue stock and Stock count dialogs on /store (API already built).

3. Hygiene register

   • 7 compliance checks with frequencies and due dates (FSSAI licence, water
     potability, pest control, cold-room temperature, food sample retention,
     deep clean, food-handler medicals).
   • Status computed on read: Ok / Warn / Overdue.
   • /hygiene page: compliance register and today's checklist.

4. Kitchen sign-off (end of week)

   • Coverage gate raised, security review, walkthrough against the prototype.

Depends on: Admin, TCP and nuvita-ui PRs merged and deployed to staging.
Decisions needed by 29 Sep: subsidy cap behaviour (A1), daily caps (A2),
hospital-run vs contracted canteen (A4).
