Fix initialization error, fullscreen exit, and settings panel styling

[Copilot]

Site failed to load due to ReferenceError: Cannot access 'originalTitle' before initialization. Additionally, nav bar wasn't reappearing on fullscreen exit, and settings panel needed rounder styling.

Changes

JavaScript initialization order fix

• Moved cmDefaultTitle and cmDefaultIcon declarations before disguisePresets object that references them
• Removed duplicate originalTitle/originalFavicon declarations

// Before: disguisePresets.none referenced undefined constants
const disguisePresets = {
    none: { title: originalTitle, icon: originalFavicon }  // ReferenceError
};
const originalTitle = 'CloudMoon InPlay';  // Too late

// After: declarations moved before usage
const cmDefaultTitle = 'CloudMoon InPlay';
const cmDefaultIcon = "data:image/svg+xml,...";
const disguisePresets = {
    none: { title: cmDefaultTitle, icon: cmDefaultIcon }
};

Fullscreen exit handler

• Nav bar now properly restores on F11 exit via fullscreenchange event

Settings panel styling

• Increased border-radius on panel (12px → 24px), inputs/selects (6px → 12px)
• Added border-radius to panic button

Original prompt
