Vertical Lift Module management

This module turns a warehouse location into a Vertical Lift Module (an automated storage tower) and lets Odoo talk to it.

• On a location you can flag it as a VLM, set vendor, address, hostname, port, user, password, a numbering sequence and a removal strategy (FIFO, LIFO or "less carrier movements").
• You define tray types (rows, columns, width, depth, height in mm) with a visual grid of cells, and individual trays attached to the VLM location. A tray shows which cells are occupied and which is the first free one.
• When a transfer involving a VLM location is validated, the system automatically creates VLM tasks: "put" tasks to store goods into a free cell and "get" tasks to take goods out. Lines for the same product and location are merged to reduce tray movements.
• A task screen (wizard) walks the operator through the pending tasks one by one, with next/previous navigation, a progress indicator, the product image and the tray cell position. Buttons let you send the command to the machine, skip a task, or record the result manually.
• If the machine reports less than requested, the task is split and the remainder stays pending; if it reports more, a warning asks for confirmation. Connection, timeout, lost-response and hardware errors are shown as clear messages.
• You can also release all trays of a VLM or call a single tray from its form.
• A VLM stock view shows quantities per tray and cell, and in inventory mode editing those quantities updates the real stock quants.

Menus appear under Inventory configuration (Vertical Lift Module: tray types, trays, quants, VLM locations) and under Inventory operations (VLM tasks). Transfers show buttons to open or perform their VLM tasks.
