Inventario: campo de precio de venta editable (faltaba en la UI)

El modelo tenia el campo price y el POS lo usa para cobrar, pero ni el
formulario de alta lo capturaba ni existia modal de edicion: los 170
articulos tenian precio en 0 y recepcion tecleaba el precio a mano en
cada venta.

- Backend: inventory_create acepta price; inventory_update lo permite
  entre los campos editables (con conversion float).
- Frontend: columna 'Precio venta' en la tabla, campo en el alta y
  modal nuevo 'Editar articulo' (nombre, precio, costo, SKU, categoria,
  unidad, niveles y notas). La existencia sigue cambiando solo via
  Ajustar para dejar registro del movimiento.
