Replaces localhost with 127.0.0.1 in devServer vue.config.js

This change seem to solve the following proxying issue:

Proxy error: Could not proxy request /api/v1/organizations?itemsPerPage=50&sortBy[]=name&descending[]=false from localhost:8080 to http://localhost:8000.
See https://nodejs.org/api/errors.html#errors_common_system_errors for more information (ECONNREFUSED).

@kevgliss can you test this when you get a change and tell me if it works for you?

For some reason, using localhost started causing issues for me. I see uvicorn running at http://127.0.0.1:8000 when I start the dev server.
