Fix rules that miss or overreach on panels

Check panel type, dimensions and material classification when hardware appears in the wrong place or goes missing.

1. When hardware is missing for a connection such as between rails and exposed panels, check the rule conditions strictly (panel type, dimensions, exposed status).

2. Correct the panel's material classification before adjusting the rules.

3. Panels can also be made parametric by setting size parameters, though manual adjustment is simpler when parameters are not needed.
