fix alumni date ranges and offboarding script

- Fixed dates for 5 undergrad alumni to show full range (start-end):
  Chelsea Joe (2024-2026), Annabelle Morrow (2025-2026),
  Jackson C. Sandrich (2025-2026), Luca Gandrud (2025-2026),
  Owen Phillips (2025-2026)
- Updated offboard_member.py to extract start year from CV and
  store full date range in alumni sheet instead of just end year
