refactor: simplify team bio — replace complex achievements with simple list, remove experience

- Replace VictoryItem (type/place/category/competition/city/date) with RichListItem (text + optional link/image)
- Remove VictoryItemListField, DateRangeField, CityField and related helpers
- Remove experience field from admin form and user profile (can be in bio text)
- Simplify TeamProfile: remove victory tabs, show achievements as RichCards
- Fix auto-save: snapshot comparison prevents false saves on focus/blur
- Add save on tab leave (visibilitychange) and page close (sendBeacon)
- Add save after image uploads (main photo, achievements, education)
- Auto-migrate old VictoryItem data to RichListItem format in DB parser
