Update email from the dashboard constituent view

For GiveCampus constituent data and imports.

The School Dashboard → Constituents screen displays contact information; it does not offer a general email Edit action. For an imported constituent, correct the email in the authoritative CRM/data source and bring it through the configured import/integration, then verify the constituent record. Keep its stable constituent ID so the update reaches the same person. Editing a donor’s login-account email is a separate workflow and does not automatically correct imported CRM contact data. For a platform-created record with no authoritative import, have support identify its source and supported update path.
