Use API keys for OPDS authentication

[h45h74x]

Hi everyone,

First of all, thank you for the amazing project! I’ve recently set up Komga for my wife and me, and using it with KOReader has been seamless.

Since I use Keycloak for SSO, I’ve noticed that OPDS still requires a traditional username/password. Currently, I have to set local passwords specifically for OPDS access. To stay consistent with an OIDC-first workflow, would it be possible to allow OPDS authentication via dedicated API keys, similar to the KOReader sync integration?

Maybe I'm missing something and this already works, otherwise thanks for considering!
