feat: add interactive exploration of Shannon's capacity formula with Plotly graphs

- Implemented bandwidth sensitivity and power sensitivity plots.
- Created a contour map for bit rate multiplying factors.
- Added input parameters for C/N and bandwidth with validation.
- Displayed computed results and sensitivity analysis metrics.
- Integrated interactive graphs for user exploration.
- Included background information section for user guidance.
