fix: Remove problematic server connectivity check from test script

Remove the complex server connectivity check that was causing HTTP handler
not found errors. The script now directly proceeds to actual testing, which
will naturally fail with clear error messages if the server is not running.

Changes:
- Replaced check_server() with simple show_server_info() function
- Removed all network probing logic (nc, telnet, curl connectivity tests)
- Simplified startup - script now shows server info and proceeds to tests
- Tests themselves will indicate if server is unreachable with clearer errors

This approach is more reliable and avoids accessing non-existent endpoints
that trigger HttpHandlerNotFoundException in the server logs.
