partner_tier_validation: Missing exceptions #2144
Description
I've encountered an issue while testing the validation process in res.partner. I believe that two exceptions should be pre-configured on the Contact model for the Stage field and the related State field. Without these exceptions, once the validation process starts, the stage cannot be changed to Active.
Another issue I found is in the fields in the res.partner module. The _partner_tier_revalidation_fields method lists several fields that should trigger a tier revalidation when changed on the form. Currently, the only active tier rule is "Is a Company is Set", and changes to the other fields listed in the method do not trigger the validation flow. Therefore, if these fields are defined in the method, they might need an exception to ensure they can trigger revalidation.
