fix(mobile): add explicit font-size to confirmation dialog body text

Add explicit font-size using rem units to confirmation dialog body text
to ensure it's readable on all screen sizes.

Changes:
- .rpg-confirm-body p: Add font-size: 1rem (base size)
- Mobile (@max-width: 768px): Override to 0.95rem for mobile screens

Previously, the body text had no explicit font-size and was inheriting
from parent, causing it to appear tiny on mobile devices. Now uses
proper rem-based sizing that scales appropriately.
