Additional context 💌

User story	B.2.13
As a…	National EPI manager
I want…	to specify stock safety buffer values for each facility in months
So that…	our forecasting can use this to calculate the maximum amount of each type of vaccine that can be expected to be stored at each facility at any point during the year

Solution B.2.13

The system will provide a mechanism for central users to enter a figure to represent the stock safety buffer in months for each facility.

This will be the number of months to represent the supply that facilities keep in reserve in case of issues with deliveries.

The interval will apply to all commodities, not to individual types of vaccine.

Note: the wording has changed from the original user story in the design doc as UNICEF clarified that

"The values are assigned at the central level guided by the iSCM/EPI policy/Manual."

There is an OG store setting that already captures this value - however we should group the supply interval value along with this safety buffer value (supply interval value doesn't exist in OG afaik)

We should display the values in OMS as non-editable so that it's easy for users to view without having to look in OG
