"Unknown vehicle variant" when enabling alpha longitudinal on Kia Niro EV 2023 (with HDA2)

### Describe the car bug

I drive a Kia Niro EV 2023 with HDA2. Ordered Harness A, had to swap CAN pairs, but then lateral worked out of the box - perfect!

However, as soon as i enable alpha longitudinal on `nightly-dev` i immediately get `unknown vehicle variant`. It should have to do with fingerprint since its a) recognised out of the box and b) i tried fingerprinting, only fwdCamera was not in the list, i added it and installed my fork but that didnt solve the issue.

Someone mentioned it might be a transitional vehicle since it **has** HDA2 (confirmed by the availability of the auto lane change) even though its a 2023 (according to list HDA2 starts from 2024).

I tested with 0.11.1 `nightly-dev`, but also with `sunnypilot-dev`

I asked on discord but without much luck. I also found other affected Niro EV 2023 drivers on reddit.
Would be amazing if someone could at least hint me where/how to check whats happening.

### Provide a route where the issue occurs

Here's a regular drive: [cdde60a79a049bf4/00000002--f448ca40b4](https://useradmin.comma.ai/?onebox=cdde60a79a049bf4%7C00000002--f448ca40b4)
And here's a short clip that i assume contains the enabling+error part: [cdde60a79a049bf4/00000001--a7d5a95c66](https://useradmin.comma.ai/?onebox=cdde60a79a049bf4%7C00000001--a7d5a95c66)

### openpilot version
