Improve error logging in theme toggle

[ahmed-abdat]

Currently, errors in localStorage operations fail silently, making debugging difficult.

Task

Add console.warn() to catch blocks for better debugging.

Location

js/theme-toggle.js - Lines 17 and 27

Current Code (Silent)

try {
  localStorage.setItem("theme", theme);
} catch (e) {}  // ❌ Silent - errors disappear

Improved Code

try {
  localStorage.setItem("theme", theme);
} catch (e) {
  console.warn("Unable to save theme preference:", e);
}

Files to Update

• Line 17: localStorage.getItem catch
• Line 27: localStorage.setItem catch

Testing

1. Test in private browsing (localStorage disabled)
2. Check console for warnings
3. Theme should still work (graceful degradation)
