TEST: Manual match by mentorship admin

[nora-weisser]

• GET /mentees/pending-manual-match (permission MENTEE_APPROVE) returns mentees with a PENDING_MANUAL_MATCH application, optionally filtered by cycleId.
• POST /mentees/{menteeId}/cycles/{cycleId}/assign-mentor (permission MENTEE_APPROVE) creates a fresh application against the chosen mentor and closes the PENDING_MANUAL_MATCH placeholder.
• POST /mentees/{menteeId}/cycles/{cycleId}/no-match (permission MENTEE_APPROVE) terminates the placeholder with NO_MATCH_FOUND. Verify it is terminal — no further transitions accepted.
• After assignment, the assigned mentor's standard accept path leads back through confirmMatch → MATCHED.
