fix(EU): update KIA/Hyundai authentication for new API endpoints

[dirkjanfaber]

KIA and Hyundai changed their EU authentication system, breaking existing login functionality with 401 Unauthorized errors. This implements the new authentication flow based on the updated API endpoints.

Changes:

• Update authentication hosts: eu-account..com → idpconnect-eu..com
• Update KIA client ID to new value (fdc85c00-0a2f-4c64-bcb4-2cfb1500730a)
• Implement new 3-step OAuth2 flow with connector session keys
• Remove language endpoint call that now requires pre-authentication
• Update token exchange to use new idpconnect-eu endpoints
• Remove unused imports and helper functions

The new authentication flow:

1. GET auth URL to extract connector_session_key from redirect
2. POST credentials to new signin endpoint with session key
3. Extract authorization code from redirect location header
4. Exchange code for tokens using new token endpoint

Fixes authentication issues for EU region KIA and Hyundai users.

Tested with KIA EU account - login, vehicle discovery, and status retrieval all working correctly.

Resolves issue #295

Thanks a lot for that !
I tried to test it with this command, but I get very little files on node_modules/bluelinky. What is the best way to install it ?
npm install dirkjanfaber/bluelinky#10fb4d8a40ff0d4344e621ef814aae03ed8eac78

Good job. You were faster then me :)

Thanks for this edit. I'm somewhat happy to see this old HTML parsing code go away.
I don't have the vehicle anymore, so I cannot test, but from a code perspective, it's ok 👍 .

@neoPix @Hacksore Can you pls bump the version and release it on NPM?

And would it be possible to also implement this PR on Bluelinky 8.3.0? Since that is the last version that runs on older Node12 (And I need that for older Homey devices).

Many thanks to everyone making this possible!!!

If the release takes longer, is there a way to get an existing installation running again?

[PierreLevres]

I think it depends on the way you are using bluelinky on the procedure how to use dirkjanfabers code. I copied his code, ran the build script and moved the new dist files to my ha server

@PierreLevres I have no idea how to do that, could you maybe share the files here?

@neoPix @Hacksore Can you pls bump the version and release it on NPM?

Sadly, I don't have the authorizations on this repository 😞

What one can do in the meantime (requires some tech knowledges) :

1. Pull the repo and use this branch.
2. npm run build
3. Copy whats in the folder /dist
   1. index.cjs and index.ems.js should be enough
4. Paste it in the node_modules/bluelinky/dist of your code project
5. It should work while waiting for the fix to be official.

[Hacksore]

This is on my radar and will get it released sometime soon.

[Hacksore]

Thanks @dirkjanfaber for the work here! LGTM and ill make a release for 10.0.0

On Hyundai EU, this resulted for me in an error: clientSecret is wrong.

On Hyundai EU, this resulted for me in an error: clientSecret is wrong.

Hyundai EU reverted to the old endpoints. So use bluelunky v10 for Kia EU and v9 for Hyundai EU.
