feat: make HTTP listen on the same IP as OTS

[gesior]

This PR makes it possible to host OTS inside docker with working HTTP server.
After changes from this commit (and #4957 ), you can run local server inside docker with server IP set to 127.0.0.1 in config.lua.
It also fixes problem described in #4945

Example docker-compose.yaml:

services:
  server:
    build:
      context: .
    restart: on-failure
    deploy:
      restart_policy:
        condition: any
        delay: 1s
    volumes:
      - .:/srv
    environment:
      MYSQL_HOST: mariadb
      MYSQL_USER: root
      MYSQL_PASSWORD: root
      MYSQL_DATABASE: tfs
    ports:
      - "7171:7171"
      - "7172:7172"
      - "8080:8080"

  mariadb:
    image: mariadb:latest
    container_name: mariadb-compose
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: tfs
    volumes:
      - ./schema.sql:/docker-entrypoint-initdb.d/01-schema.sql
      - ./docker/data.sql:/docker-entrypoint-initdb.d/02-data.sql
    ports:
      - "3306:3306"

docker/data.sql file to create account tfs@tfs with password tfs and character GOD:

INSERT INTO `accounts` (`id`, `name`, `password`, `secret`, `type`, `premium_ends_at`, `email`, `creation`) VALUES ('1', 'tfs', 'e65018eee3ab1e3ecdfc67a91a2aa327434ab5b5', NULL, '6', '0', 'tfs@tfs', '0');

@Shawak can you confirm this solves the initial issue with Docker?

[Shawak]

I didnt test it but it should since the game server now binds on ip address any (not sure if it only works for ipv6 ipv4 tho)

(not sure if it only works for ipv6 tho)

Tested on Windows (.exe) and using Docker with Linux container, in both cases bind to ip::address_v6::any() worked with login to 127.0.0.1. It's the same code all other ports use (7171/7172).
