fix: correct userInfo sizing at desktop narrow and prevent character widget expansion

UserInfo Widget:
- Changed from column-based to mobile detection (window.innerWidth <= 1000)
- Desktop narrow (2-col) now correctly uses 1x2 instead of 1x1
- Mobile devices still use 1x1 compact mode with round avatar
- Ensures vertical layout at all desktop widths

PresentCharacters Widget:
- Changed maxAutoSize to match defaultSize (3x2 on desktop)
- Prevents auto-expansion to 3 rows during layout
- Stays at 2 rows to fit 1080p screens without scrolling

Fixes responsive sizing issues on desktop narrow panels.
