- Remove all || «عدد» / || "unit" fallbacks: materials/line items without
an explicit unit now fail with a clear Persian error instead of silently
creating an «عدد» unit row (POST /units happens only for typed names).
- unitIdByNameOrCreate/createUnit guard empty names; code = normalized
typed name only.
- Add api.materialUnits (list/create/update/remove with brand_material_id),
api.brandMaterials (list by material + link), materials.updateCanonicalUnit,
apiV26.catalog.* unit/brand/material creation helpers (shared usage).
- Accept payload: each chosen item_decision now carries the selected single
project_id so backend can bind decision.project_id (PM on-the-way
segregation).
