Added FOCUS-60352 - Online Enrollments: Fix missing applicant matches in Add a Student wizard

When the system preference to show applicants in exact and partial matches on the Add a Student wizard is enabled, applicants now appear correctly in search results when processing an unprocessed application through Online Enrollments. Previously, searching by name or birth date returned no results in this workflow despite the preference being enabled. Applicants from prior school years also appear as expected when the district's default year has been advanced.
