ddmrp_coverage_days

Purpose

Provides DDMRP buffers with a computed indicator showing available stock coverage in days.

Features

stock.buffer: Computes a coverage_days metric by dividing the non-reserved on-hand quantity by the buffer's average daily usage and rounding with the product UoM precision.
stock.buffer: Exposes the days of coverage field in buffer form and list views so planners can see it alongside existing stock figures.
