fix(dashboard): Invalid owner's name displayed after updates

[justinpark]

Fixes #30259

SUMMARY

The action DASHBOARD_INFO_UPDATED changes the first_name and last_name properties of the owner to a full_name property [#17570].

However, the display change logic for the full_name property is only applied in the property modal, resulting in an error where other code referencing the owner outputs undefined.
To resolve this issue, the same Owner type and display getter function have been applied in the affected code.
