Feature/issue 203/url global variable

[vladislav-k1]

Issue(s):

#203

Type of change:

• New feature

Description:

• The backend URL is now stored in frontend/src/assets/globalConstants.js and is referenced across entire frontend code instead of hardcoded strings.
• By default, the backend port is 8080 and SSL is disabled by default. This behavior is overwritten in the CD runner.
• Docker image is now using bind mounts to link the keystore.p12 file for deployment.
• startServer.sh has been replaced with localExecute.sh to assemble frontend and execute the backend locally.

Additional context:

Pay extra attention to the CD runner.

Testing instructions:

For local execution:

1. Checkout to this branch, merge from dev.
2. Initialise the backend using the new localExecute.sh script.

For CD process validation:

1. Push this code to the GHCR.
2. Pull the image from GHCR to the server.
3. Run the image in the container using the following parameters: -p 443:443 ghcr.io/spe-uob/2024-ailearningtool:latest -v keystore.p12:/keystore.p12

The local execution works as intended. Unfortnately, I think the only way to test the CD would be to push to dev, but the changes you made to deploy-ghcr.yml make sense so I believe it would work.

Local execution works. Pushing to dev to test CD.
