refactor(webui): enhance network visualization in network.html

[skrashevich]

Commit Summary:

• www/network.html: The visualization implementation using the vis library in network.html was significantly enhanced. Changes include introducing physics settings and layout configurations, handling data fetching within a function to update the network graph periodically, and utilizing error handling for fetch operations. The periodic update functionality with intervals was added to keep the visualization current. A new variable network was introduced to manage states, supported by better positioning and responsive design adjustments.

• internal/streams/dot.go: The label function was refactored to use strings.Builder for constructing the output string, enhancing performance and readability. Previously concatenated strings were replaced with builder's WriteString method.

Dependency Note:
This commit should best be merged after #1195, although it does not strictly depend on it.

Network pan and zoom doesn't stored. And also sometimes networks moves down by 1 pixel on each update.
