feat(traffic-flow): enhance traffic flow analytics and overlay configuration

- Updated the traffic flow analytics to include new state variables for named bytes, total bytes, and window seconds, improving data granularity.
- Modified the NetworkMapPage to display classified traffic data, including a new section for showing classified and total bytes.
- Enhanced the applyFlowOverlay function to support a new option for disabling GRE fast path, allowing for more flexible traffic flow configurations.
- Added a toggle in the FlowOverlaySheet component to enable or disable the GRE fast path setting, improving user control over traffic processing.
- Updated tests to validate the new functionalities and ensure accurate traffic flow analytics.
