feat: use OED authentication

[bodom0015]

Problem

CLEANDB-frontend prototype is currently publicly accessible

We would like this to be behind the same (temporary) auth wall that is currently used by OpenEnzymeDB

Approach

• feat: adjust URL patterns to share cookies between CLEANDB and OED prototypes
• feat: add private-auth/errors middleware to redirect without auth

TODOs:

• add middleware to CLEANDB-api

How to Test

NOT CURRENTLY DEPLOYED

Staging:

1. Close all incognito windows, and open a fresh incognito window
2. Navigate to CLEANDB staging: https://cleandb.staging.openenzymedb.mmli1.ncsa.illinois.edu
   • You should be prompted to login in with Keycloak
3. Log into Keycloak using CILogon or username/password
   • If your account is in the correct Keycloak group (openenzymedb), you should be routed to the CLEANDB frontend
   • If your account is not in the correct Keycloak group (openenzymedb), you should be shown a 403: Forbidden error page

Production:

1. Close all incognito windows, and open a fresh incognito window
2. Navigate to CLEANDB prod: https://cleandb.openenzymedb.platform.moleculemaker.org
   • You should be prompted to login in with Keycloak
3. Log into Keycloak using CILogon or username/password
   • If your account is in the correct Keycloak group (openenzymedb), you should be routed to the CLEANDB frontend
   • If your account is not in the correct Keycloak group (openenzymedb), you should be shown a 403: Forbidden error page

This PR should not change the Docker image build, so the following error does not affect this PR at all

However, I did notice a problem with the image build - filed this as a new issue:
#4
