feat(raw-materials): wax and propolis lots consumed by production batches

- RawMaterialLot (beeswax, propolis) in grams with origin (apiary,
  harvest); stock in the same movement ledger: withdrawals, inventory
  counts, and the new movement type CONSUMPTION.
- Production batches take inputs (raw lot + grams); batch and consumption
  are one transaction, never more than a lot has left. Deleting a
  mistaken batch gives the material back as its own movement.
- Traceability both ways: batch -> inputs, raw lot -> usedIn.
- Movement belongs to exactly one of bottling / production / raw lot
  (CHECK); raw material changes do not trigger the shop webhook.
- Permissions raw-material:*, granted to roles that maintain production
  batches.
