chatapi: smoother port number (fixes #8760)

[Mutugiii]

Fixes #8760

• Update the chatapi port to 5400, switching from 5000
• Update the docker readme file

To test:
First stop the chatapi docker container using

• docker desktop or
• docker stop planet-chatapi-1 or docker stop {{id}} if using the planet chatapi container id(docker ps to find it)

Create a .env file in the chatapi with the following env:

  SERVE_PORT=5400
  COUCHDB_HOST=http://localhost:2200
  COUCHDB_USER=username
  COUCHDB_PASS=password

Then (if you don't have node 18 installed run nvm install 18 or fnm install 18):

  cd chatapi
  nvm use 18 // fnm use 18 
  npm run dev

Visit localhost:5400/checkproviders to confirm

Maybe it's just me, but my Chatapi folder had a .env file, where I had to edit the SERVE_PORT variable or else it still fell back to port 5000. Running normally on 5050 now though.

Thanks! Added this step to the testing instructions

[Mutugiii]

After discussions, moved from 5050 to 5400

Tested on

• planet uriur rpi
• planet uriur clone

Also updated the wiki development instructions to reflect this change: open-learning-exchange/open-learning-exchange.github.io#3626

Now I meet this problem when testing. I am tring to figure out the problem

Looks good! As a note the gists will need to be updated for production as well as development in the 10 steps to use 5400.

@Mutugiii the code is fine but we already have to many production systems
