Add Dynamic Shape 2 page with unicode-based angles and line flipping

[Copilot]

This PR implements a new "Dynamic Shape 2" page that creates dynamic line patterns using unicode-based angles with conditional line flipping logic.

Changes Made

New Page: Dynamic Shape 2

• Route: /dynamic-shape-2
• Navigation: Added menu entry for easy access
• Functionality: Generates connected lines based on text input, similar to the original Dynamic Shape page

Key Differences from Original Dynamic Shape

1. Unicode-based Angles: Uses the unicode value directly as the angle instead of incremental 180-degree rotations

   // Original: double angle = currentAngle + (i * 180);
   // New: double angle = unicode;

2. Line Flipping Logic: Flips lines that point away from both center lines

   bool pointsAwayFromVerticalCenter = Math.Abs(proposedEndX - centerX) > Math.Abs(currentX - centerX);
   bool pointsAwayFromHorizontalCenter = Math.Abs(proposedEndY - centerY) > Math.Abs(currentY - centerY);
   
   if (pointsAwayFromVerticalCenter && pointsAwayFromHorizontalCenter) {
       angle += 180; // Flip the line
   }

Technical Implementation

• Center Lines: Vertical at x=250, horizontal at y=200 (canvas center)
• Flipping Condition: Line is flipped if it moves further away from both center lines
• Preserved Features: Color generation, line width variation, bounds checking, and visual styling remain consistent with the original

Testing

• ✅ Build passes successfully
• ✅ Application starts without errors
• ✅ Navigation menu updated correctly
• ✅ New page accessible at /dynamic-shape-2

The implementation provides more varied and character-dependent line patterns while maintaining the connected line drawing behavior of the original Dynamic Shape page.

Fixes #13.
