Verify - MHR - Home Owners component validations for Registration/Transfers

**See notes from Dima and Tracey in comments**

VERIFY
- [ ] In the Transfer due to sale or gift type for Tenants in Common structure, when a user deletes one of the owner in a group and adds a new owner, then the validation "Group cannot have a mix of owner, executor, administrator and bankruptcy trustee roles." is displayed and stops user from navigating to the review screen.

- [ ] When filing an MH registration, if the home owners table has mix of owners, then the validation is displayed as expected but the stepper is validated with green checkmark.

- [ ] In the Transfer due to sale or gift type for Tenants in Common structure, when a user adds a new owner to a group, then the validation "Group cannot have a mix of owner, executor, administrator and bankruptcy trustee roles." is displayed in both the groups and stops user from navigating to the review screen.

Start with the Home Owners component and reproduce the three registration and transfer scenarios described in the issue, including the group-role validation and stepper state. Done means the validation appears in the expected groups, blocks navigation to review when required, and the stepper does not show a green checkmark for an invalid step.
