feat: structured victories/education with photos, links, and editorial profile layout

- Add VictoryItem type (place, category, competition, location, date, image, link)
- Add RichListItem type for education with image/link support
- Backward-compatible DB parsing for old string[] formats
- Admin forms with structured fields and image upload per item
- Victory/education cards with photo overlay and lightbox
- Remove max-width constraint from trainer profile for full-width layout
