FloPinguin 74b3bd275b Allow mappers to omit nation coordinates in manifest.json for random spawn 🎲 (#4156)
## Description:

Previously, every nation in a map's manifest.json required explicit
coordinates. Additional nations already supported optional coordinates
to trigger random spawn placement, but regular nations did not.

Idea from PlaysBadly.

Reasoning (copied off discord):

> I've been working on World Inverted by adding realistic 'nations' in
the form sunken ship names with their flags and location. However after
searching around for other possible nation locations that are ocean
related I realised that I might not have enough info for proper
'realisitc' coverage of the map. Currently Im at ~170 nations with
cordinates. This is not including the additional nations with no
locations. This will be reduced to ~62 as the default with the rest
turning into additional nations.
> 
> The problem is the end process is proving difficult. Trying to blance
the nation placment on the map is a little much at this volume. So being
able to add a few no-cordinate nations would be a great way to fill in
the map.

This PR also improves the MapConsistency test to check the additional
nations too.

## Please complete the following:

- [X] I have added screenshots for all UI updates
- [X] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [X] I have added relevant tests to the test directory

🌟 Features

  • Real-time Strategy Gameplay: Expand your territory and engage in strategic battles
  • Alliance System: Form alliances with other players for mutual defense
  • Multiple Maps: Play across various geographical regions including Europe, Asia, Africa, and more
  • Resource Management: Balance your expansion with defensive capabilities
  • Cross-platform: Play in any modern web browser

📋 Prerequisites

  • npm (v10.9.2 or higher)
  • A modern web browser (Chrome, Firefox, Edge, etc.)

🚀 Installation

  1. Clone the repository

    git clone https://github.com/openfrontio/OpenFrontIO.git
    cd OpenFrontIO
    
  2. Install dependencies

    npm run inst
    

    Do NOT use npm install nor npm i but instead use our npm run inst. It runs the safer npm ci --ignore-scripts to install dependencies exactly according to the versions in package-lock.json and doesn't run scripts. This can prevent being hit by a supply chain attack.

🎮 Running the Game

Development Mode

Run both the client and server in development mode with live reloading:

npm run dev

This will:

  • Start the webpack dev server for the client
  • Launch the game server with development settings
  • Open the game in your default browser (to disable this behavior, set SKIP_BROWSER_OPEN=true in your environment)

Client Only

To run just the client with hot reloading:

npm run start:client

Server Only

To run just the server with development settings:

npm run start:server-dev

Connecting to staging or production backends

Sometimes it's useful to connect to production servers when replaying a game, testing user profiles, purchases, or login flow.

To replay a production game, make sure you're on the same commit that the game you want to replay was executed on, you can find the gitCommit value via https://api.openfront.io/game/[gameId]. Unfinished games cannot be replayed on localhost.

To connect to staging api servers:

npm run dev:staging

To connect to production api servers:

npm run dev:prod

🛠️ Development Tools

  • Format code:

    npm run format
    
  • Lint code:

    npm run lint
    
  • Lint and fix code:

    npm run lint:fix
    
  • Testing
