This RCF to propose a POC implementation for the following

The goal is to support Vertical Lift such as Kardex or similar systems. We'll first implement a base layer to cover all kind of vertical automated storage, but then we'll implement the Kardex layer on top of it. Other might contribute to other similar system.

Odoo in that case will drive the machine and the operator to place goods an retrieve them. In this design the machine don't know where is what, only Odoo does.

It adds a stock location structure for the Vertical Lift "shelves", with different levels:
Vertical Lift → Shuttles → Trays → Cells. The Cells are automatically generated from Tray Types (example: 4 cols and 2 rows) selected on the trays.

A visual representation of a tray displays the selected cell and color the cells that contain stock.

The initial proposal assumes that each Shuttle will be driven by a screen displaying the operations to do (pick or put, inventory will need some work as well). Here's the (incomplete) dedicated UI, with the information about the product to pick + visualization of the tray and cell to pick.
