Fix: qSVG polygonize - polygons creation condition

[mislavivanda]

🐞Current Issue

A condition in the qSVG.polygonize() method always resolves to true because it compares an array(realCoords.outside) with a number(realCoords.inside.length). This leads to incorrect handling of detected polygons.

✅Test Steps

1. Start the app from master branch
2. Create a basic square floorplan from initial modal
3. Click CONFIG. ROOMS option in the left panel
4. Hover over the room

🔎You should see a yellow-highlighted room area. Currently, its edges run through the center of the walls.
✅Our intended behavior is for the room area to match the interior edges of the walls. This commit fixes that.

🛠️polygonize() Method Overview

The goal of the polygonize() method is to detect polygonal regions by analyzing wall segments and constructing a graph in which it detects closed loops. These loops are evaluated, and if they meet certain conditions (not marked with bypass = 1), they are pushed into the polygons array as candidates for rooms.
The condition in question is intended to verify whether the detected loop forms a proper room polygon. This is also hinted in the inline comment:

// REAL INSIDE POLYGONE -> ROOM

The check attempts to confirm that the loop is symmetrical and well-formed by comparing the inside and outside coordinate sets. If both arrays have the same length, it suggests a clean, closed shape, and realCoords.inside can be trusted.
If they don't match, the method still includes the shape, but uses a fallback approach by using coords array. These fallback polygons can still be useful, but are considered less reliable with lower confidence and precision compared to the properly closed loops. They can be interpreted as approximated closed shapes that might not perfectly align with actual room boundaries.

✅Proposed fix

Update the condition to correctly compare the lengths of the inside and outside arrays:

if (realCoords.inside.length != realCoords.outside.length)

This simple fix aligns with the original intent, and ensures proper validation of real, symmetrical room polygons.
