Refactor documentation and code for clarity and consistency

- Updated README files to use "2D" instead of "two-dimensional" for consistency across examples.
- Modified advectionDiffusion1D.js to change boundary conditions and improve comments for clarity.
- Adjusted heatConduction2DFin README to reflect the "2D" terminology.
- Enhanced FEAScript.js to store coefficient functions in the model and updated the setSolverConfig method accordingly.
- Improved generalFormPDEScript.js to clarify comments on diffusion, advection, and reaction terms, and added error handling for unsupported 2D cases.

-## Heat Conduction in a Two-Dimensional Fin
+## Heat Conduction in a 2D Fin
 
 This example demonstrates solving a steady-state heat transfer problem in a 2D rectangular domain using the FEAScript library. The problem represents a typical cooling fin scenario, where the objective is to model heat conduction and understand temperature distribution under specific boundary conditions.
