fix(userInfo): fix avatar 404 errors and improve layout/scaling

**Avatar 404 Fix:**
- Add fallback to getUserAvatar() call to use FALLBACK_AVATAR_DATA_URI when user avatar is missing
- Prevents 404 errors on app startup or when no character is selected

**Layout & Space Utilization Improvements:**
- Implement flexible hybrid layout system:
  - 1 column (1x1): Centered large avatar (3rem) with text below
  - 2+ columns (2x1+): Side-by-side (avatar 2.5rem left, text right)
- Replace rigid horizontal layout with adaptive container
- Add layout classes: rpg-layout-vertical, rpg-layout-horizontal
- Trigger onResize on initial render for correct layout

**Better Styling:**
- Increase avatar size: 2.5rem-3rem (was 1.2rem)
- Increase font sizes: 0.9rem name, 0.85rem level (was 0.75rem)
- Improve text hierarchy with proper containers
- Add proper spacing and alignment for both layouts
- Remove awkward vertical stacking of "Name | LVL 1"
- Text now stacks cleanly: "Name" on one line, "LVL X" on another

The widget now uses space efficiently, displays a prominent avatar,
and adapts intelligently to different widget sizes.
