Basic Authentication not working as intended

[pedro-cf]

Describe the bug
The Basic Authentication implementation in stac-fastapi-elasticsearch is not working as expected. When configuring multiple user credentials through STAC_FASTAPI_ROUTE_DEPENDENCIES, the authentication fails even with valid credentials.

To Reproduce
Steps to reproduce the behavior:

1. Configure basic auth with multiple users in docker-compose.yml:

- STAC_FASTAPI_ROUTE_DEPENDENCIES=[{"routes":[{"method":"*","path":"*"}],"dependencies":[{"method":"stac_fastapi.core.basic_auth.BasicAuth","kwargs":{"credentials":[{"username":"admin","password":"admin"}]}}]},{"routes":[{"path":"/","method":["GET"]},{"path":"/conformance","method":["GET"]},{"path":"/collections/{collection_id}/items/{item_id}","method":["GET"]},{"path":"/search","method":["GET","POST"]},{"path":"/collections","method":["GET"]},{"path":"/collections/{collection_id}","method":["GET"]},{"path":"/collections/{collection_id}/items","method":["GET"]},{"path":"/queryables","method":["GET"]},{"path":"/queryables/collections/{collection_id}/queryables","method":["GET"]},{"path":"/_mgmt/ping","method":["GET"]}],"dependencies":[{"method":"stac_fastapi.core.basic_auth.BasicAuth","kwargs":{"credentials":[{"username":"reader","password":"reader"}]}}]}]

2. Start the stac-fastapi-elasticsearch service with basic auth configuration:

docker-compose up -d

3. Try to access the root endpoint with valid credentials:

curl --request GET \
  --url http://localhost:8080/ \
  --header 'Authorization: Basic YWRtaW46YWRtaW4='

curl --request GET \
  --url http://localhost:8080/ \
  --header 'Authorization: Basic cmVhZGVyOnJlYWRlcg=='

4. Receive error response:

{"detail":"Incorrect username or password"}

Expected behavior

• The API should accept valid credentials from any user configured in the route dependencies
• Both "admin:admin" and "reader:reader" credentials should work for their respective configured routes
• When a route is configured for multiple users, any of their credentials should work

Environment:

• OS: Ubuntu 22.04.4 LTS
• Docker version: Docker version 27.1.1, build 6312585
• stac-fastapi-elasticsearch version: 3.2.0
• Python version: 3.10
