Add FDR-correction snippets to graph-analysis scripts

[yu-wei-c]

Is your feature request related to a problem? Please describe.
In the graph-analysis example scripts (e.g., example_CON_WU, example_FUN_BUD), the script shows how to calculate measures and run group comparisons (differences and p-values). However, it does not show how to apply FDR correction, even though the GUI tutorial covers this step.

Describe the solution you'd like
Add a minimal FDR-correction snippet to each example script that performs group comparisons, demonstrating how to obtain FDR-adjusted p-values and a significance mask

Additional context
For instance, in example_CON_WU, after computing p-values for degree:

% FDR correction 
q = 0.05; % Typical choices: 0.01, 0.05, 0.10
[p_adj_p1, mask_deg_WU_p1] = fdr(cell2mat(degree_WU_p1).', q);
[p_adj_p2, mask_deg_WU_p2] = fdr(cell2mat(degree_WU_p2).', q);
