Optimize node layout: reduce prompt heights and fix canvas overflow

- Limit multiline prompt widgets to 60px height (~3 lines) with scrolling
- Increased minHeight from 200 to 600 to prevent canvas extending beyond node
- Prompts now more compact while remaining fully functional
- Applies to both RegionalPrompterSimple and RegionalPrompterFlux
