feat: add CLI for server config

Introduced argument parsing to provide command-line options for configuring the server port and enabling debug mode, enhancing flexibility for local development or deployment needs. The changes include adjusting string quotes for consistency and minor formatting improvements.

This addition allows users to start the web server with custom configurations without modifying the source code directly, making it more convenient to run in different environments or debug as needed.
