Clearer customization with new Appearance and Auto-Fixes tabs

We wanted to make customizing your experience more intuitive, so we've split the old 'Customize' tab into two distinct areas: 'Appearance' and 'Auto-Fixes.' The 'Appearance' tab now focuses solely on widget styling, helping you find all the visual tweaks in one place without distractions.

**Dedicated space for automation**
The new 'Auto-Fixes' tab groups together all automatic fixes and AI-powered enhancements, giving you a clearer view of these helpful tools. We've also updated the information about how often auto-scans run, so you'll know they happen every two hours.

**Smarter rate limit info**
To keep things smooth and transparent, the rate limit now resets at the top of each hour rather than on a rolling window. You'll see accurate timing for when limits refresh, preventing any confusion. Altogether, these changes make managing your settings simpler and more user-friendly.
