Dark background + glowing kid cards + parent dashboard card on student home

- Student home gets a deep navy-to-indigo background so card glows pop
- Each kid card glows its own theme color via ::after blur pseudo-element with breathing animation; hover cranks it up to full brightness
- Floating school emoji opacity increased for visibility on dark bg
- 'Parent dashboard' link replaced with a frosted-glass card button
