Refine light cream theme design and add simulator fallback

- Redesigned styles.css to apply a clean, light cream layout with soft shadows and slate-charcoal typography.
- Standardized form elements, borders, and result status badges to match the warm-themed colors.
- Modified the wallet connector code inside MidnightContext.tsx to support a seamless Simulator Mode fallback when the Lace extension API is absent or blocked in the browser.
