Flag remove

[jonathanMweiss]

Flag removal + fixes on scripts to run LKG and DKG on the local machine (helpful when we want to test DKG binary correctness and output).

Pull Request Overview

This PR removes the tssNetworkSocketPath command-line flag and refactors the TSS network server creation to automatically determine the socket path from the guardian's identity. The changes enable better local testing of DKG (Distributed Key Generation) functionality.

Key Changes:

• Removed tssNetworkSocketPath flag and parameter passing throughout the codebase
• Modified NewServer to automatically derive socket path from the TSS messenger's identity
• Added test infrastructure for running DKG locally with configurable parameters
