Fix: Simplify output and add UI text display

Changes:
- RETURN_TYPES changed to single IMAGE output only
- Removed separate width/height outputs
- Added UI text display with resolution info
- Returns dict with 'ui' and 'result' keys
- Shows mode, resolution, and filename in UI

This should fix preview display and provide better UX
with resolution info shown as text in the node.
