[BUG] when changing GENERIC_NAME to other then the default value (generic) is being ignored for services that uses traefik middlewares

Describe the bug
traefik setup.

services:
  tinyauth:
    image: ghcr.io/steveiliop56/tinyauth:v3
    environment:
      - APP_URL=https://auth0.example.com
      - GENERIC_NAME=MyGenericName #default:. generic
    deploy:
      labels:
        # defining the labels for other services:
        - "traefik.http.middlewares.tinyauth-auth0-secure.forwardauth.address=http://tinyauth:3000/api/auth/traefik"
        - "traefik.http.middlewares.tinyauth-auth0-secure.forwardauth.authResponseHeaders=remote-user, authorization"
        - "traefik.http.middlewares.tinyauth-auth0-secure.forwardauth.trustForwardHeader=true"

i can call the tinyauth just fine and authenticate with my OIDC endpoint (OpenText Advanced Authetication).

now i add the middleware to another service

services:
  homer:
    deploy:
      labels:
        - "tinyauth.domain=swarm0.example.com"

if i call now swarm0.example.com i get presented with the tinyauth webui -> press the now called "MyGenericName" button and a redirect is shown in the url bar which has a callback to auth0.example.com... callback...generic in it that is not working (should be MyGenericName)

the redirect to MyGenericName works with the tinyauth WebUI but not with the other service that uses a middleware via label.

if i comment GENERIC_NAME (and adapt the OIDC provider setting to generic) then both work

Hello,

The config option GENERIC_NAME is just an option to customize the name of the OAuth button in the login screen, nothing more. It isn't being used anywhere in the OAuth logic. This will be changed with #355 that will completely overhaul the OAuth logic.
