Issue #2: Dynamic Data Schema & Multi-Dimensional Scoring

[genes3e7]

Description: Deprecate the hardcoded Score column. The system must support $N$ continuous score dimensions (Score1, Score2, ...) and calculate the objective function using a weighted sum of absolute deviations.

Technical Tasks:

• Refactor src/core/data_loader.py to identify all columns matching a continuous score pattern.
• Update src/ui/steps.py to dynamically generate numeric inputs for the weightage $W_n$ of each detected score column.
• Update src/core/solver.py objective function: Calculate the absolute deviation for each dimension independently, multiply by the user-defined weight, and minimize the sum of all weighted deviations.
• Refactor UI table renderers (results_renderer.py and exporter.py) to display $N$ score columns instead of one.
