Feat/proxy api

[LoTerence]

Changes

Key feature:

• vite dev server can now proxy api requests to the django dev server

Other changes

• fixed eslint errors: import.meta.env ts error and cookiebanner props.children not being used

Note

All devs need to add django to their dev.env files, so that docker can proxy frontend requests to the django server container:

DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 [::1] django

This only needs to be done in the dev environment.
