fix(modal): resolve button font-size CSS cascade conflict

- Scope modal button selectors to prevent dashboard styles from overriding
- Use .rpg-modal and .rpg-confirm-modal prefixes for higher specificity
- Desktop modal buttons: 1rem (consistent, readable)
- Mobile modal buttons: 1.05rem (touch-friendly)
- Dashboard buttons unchanged: keep 1.4vw viewport-based sizing
- Fixes buttons being too large on desktop (~27px) and too small on mobile (~5px)
