feat: improve trainer bio UX — reorder sections, collapsible, scroll arrows, card hover

- Reorder: Groups → Description → Education → Achievements
- Education and Achievements are collapsible (collapsed by default)
- Section headings now gold instead of gray
- Scroll arrows (left/right) replace fade indicators, always visible
- Bigger cards (w-60), wider image thumbnails
- Card hover: gold border glow, brighter text, subtle shadow (user side)
- Admin cards: hover highlight + focus-within gold border for active editing
- Auto-add draft item on blur to prevent data loss
