Stock Location Release Channel Restriction

This module adds release channel restrictions to storage locations. On each location you can set a restriction rule: either 'mixed' (movements from different release channels are allowed) or 'same' (only movements from the same release channel are allowed). The rule can be set specifically on a location and is automatically inherited by its child locations.

When a location is restricted to 'same', the system remembers the release channel of the first incoming move and blocks any later move from a different channel. A warning banner appears on the location form showing which channel currently restricts it. You can also filter locations that have an active restriction from the location search view.

When a transfer is validated, the module automatically sets or removes the location restriction based on the release channel of the outgoing delivery. If all pending outgoing moves are completed, the restriction is removed. A wizard called 'Reset Release Channel' lets you manually clear the restriction on selected locations, optionally including other locations of the same family.

The module touches stock.location, stock.move.line and adds the wizard model stock.location.reset.release.channel. It adds fields and buttons to the location form and list views, and a server action 'Remove Release Channel' available from the location list.
