TEST: Website mentor list

[nora-weisser]

• Returns all ACTIVE mentors. PENDING and REJECTED mentors never appear.
• GET /mentors accepts these optional query params: keyword, mentorshipTypes, yearsExperience, areas, languages, focus.
• Type filter cases:
  • ?mentorshipTypes=AD_HOC returns mentors with non-empty menteeSection.adHoc; excludes long-term-only.
  • ?mentorshipTypes=LONG_TERM returns mentors with non-null menteeSection.longTerm; excludes ad-hoc-only.
  • ?mentorshipTypes=AD_HOC,LONG_TERM returns the union — a mentor offering only one type still appears.
  • A mentor offering both appears in both single-type filters.
• When the open cycle is CLOSED, the response still returns active mentors but skips the cycle-specific availability projection. Verify response shape.
• Apply-button rule can be rendered client-side from the existing payload (for ad-hoc and both) — no extra call required.
