[FIX] mrp: Add support for picking replenishment in MO Overview

When a reception picking was created to resupply a component (without
using a purchase order), the picking was correctly linked in the MO
Overview, but the date was set as "Not available" as the planned date of
the picking wasn't read.
Also adds the color scheme for pickings states for the Overview.
