Feature: Send command to devices (planning) - screen controls

[judramos]

Is your feature request related to a problem? Please describe.
If a layer is linked to a planning created for a device model, it is possible to link devices of another type (device model).
The scheduler will send a command to a device that can't treat it.

Describe the solution you'd like
Should add the following controls on screens :

• Link a device to a layer : if the layer is already linked to a schedule, only display devices of the good device model (defined in the planning)
• Planning edition : only allow to link layers with no devices or with the good devices model already linked
• It should not be possible to link two different device models to the same layer

Describe alternatives you've considered
N/A

Additional context
The device model (so the list of commands available) can't be modified on an existing planning.
