[FIX] crm: reset dashboard_graph_model on uninstall

Before this commit:
    * Install `sale_management`, `crm`
    * Uninstall `crm`
    * Go to sales -> sales channels
    * Boom! The view is broken

This happens because both CRM and Sales share the sales teams view, yet
CRM's override of the model adds a selection_add to the
dashboard_graph_model selection field, when it is uninstalled, records
whose dashboard_graph_model field are set to one of the values
introduced by CRM keep this no-longer-valid value and upon accessing the
view it crashes.

This is a known limitation of selection fields and the selection_add
feature.

To solve this, an uninstallation hook has been created for CRM which
will fetch all records whose dashboard_graph_model is set to
`crm.opportunity.report`, and update the field of all these records to
None (NULL).

Fixes #25363
