OIDC Support - Attempt 2

[lenaxia]

Description

This PR rebases the oidc changes to the current Overseerr mainline (develop), and fixes some improper OIDC implementation. Because of this, it now works with authelia. Changes have also been revalidated to work with a basic configuration of Authentik. I have not tested this with other OIDC providers.

Fixes include:

• Adding support for scope and error parameters in the oidc-callback endpoint (these are all optional parameters)
• fixing callback redirect_uri protocol generation to base on the initiating protocol, as opposed to assumping https, which is what it did previously
• add support for the aud (audience) callback parameter being an array. the OIDC spec allows aud to be either a string, or an array of strings. Previous implementation here only allowed string when doing a oidc validation. This is now fixed to support both string and array
• Added improved logging and error handling to make future debugging easier.
• change default logging level to be info if LOG_LEVEL env variable is not defined (previously was debug)
• Improved JWT token validation robustness

Bug Fix:

• Plex New Login button was incorrectly tied to the localLogin settings flag. It also was disabled unnecessarily and did not match the formatting of the local login (and now OIDC) buttons. This has been fixed.

To-Dos

• Successful build yarn build
• Translation keys yarn i18n:extract
• [-] Database migration (if required)

Issues Fixed or Closed

• Fixes: feat: oidc support #2792

@sct Let's try this again, this should only include the OIDC changes now, plus some small bug fixes.

Okay, addressed eslint and logging injection attack. Further, improved middleware logging to scrub sensitive data from log messages and sanitize against injection attacks.

@sct got eslint passing (for code I touched) and addressed log injection risk.

[lenaxia]

Not stale

@sct can we get someone to look at this?

[lenaxia]

merged latest develop into the branch.

I've just tested this fork with my Authelia setup, and it works; thank you, @lenaxia, for the docker image and for keeping this PR up to date.

Some quick thoughts after using this:

• The setting "Enable New Plex Sign-In (Allow Plex users to sign in without first being imported)" could be changed to include OIDC users that log in.
• I would love it if there was a way to disable sign-in via Plex to only allow OIDC logins, just like there is an option to disable local logins. (The logic could allow admins to disable sign-in methods like local, Plex, and OIDC as long as one method is enabled).

@sct is there any reason why this PR isn't being accepted?

[Edit: I realised you might be waiting for #3015 to be merged before accepting this one - thanks for your work on this cool project. I recognise you are doing this in your spare time, so please don't take my comment as an attempt to hassle you. More to understand the logic/sequence you had in mind.]
