Bassa UI is hardcoded to send the request to 'localhost:5000/api'

[agentmilindu]

Describe the bug
in the Bassa frontend code, it is hardcoded to send the requests to the 'localhost:5000/api'. This needs the Bassa API running on the user's localhost, which is very wrong.

To Reproduce
Steps to reproduce the behaviour:

1. Run Bassa UI in production mode ( not in develop mode with Gulp. Run with the Docker. )
2. Observe the API calls

Expected behaviour
API URL should be configurable in the frontend when the fronted Docker is run, like via an ENV variable passed to the Docker.
Then the frontend should be sending the API calls to this configured URL.
