feat: add trainer bio (experience, victories, education) across all layers

- Extend TeamMember type with experience/victories/education string arrays
- Add DB columns with auto-migration for existing databases
- Update API POST route to accept bio fields
- Add ListField component for editing string arrays in admin
- Add bio section (Опыт/Достижения/Образование) to team member admin form
- Create TeamProfile component with full profile view (photo + bio sections)
- Add "Подробнее" button to TeamMemberInfo that toggles to profile view
