[GRDM-60941] Fix: auto-input range for Read IdP Profile

[ndnhat1]

Purpose

The purpose of these changes is to allow the "Read IdP Profile" button on the Employment tab to automatically populate Japanese-language fields (institution_ja, department_ja) from the IdP (Shibboleth) attributes stored at login.

Changes

• Store Japanese IdP attributes in frontend ViewModel — Update ListViewModel.unserialize() to store idp_attr_institution_ja and idp_attr_department_ja from the API response, in addition to the already-stored idp_attr_institution and idp_attr_department.
• Apply Japanese IdP attributes on "Read IdP Profile" — Update ListViewModel.setContentFromIdP() to write institution_ja and department_ja into the content model when the corresponding IdP attribute is non-empty.
