Vendors seems to be hardcoded and updating providers/ entries don't get picked up on rebuild

[xavbart]

The list of vendors is statically given in the following files :

AddKeyForm.tsx
DeleteKeyModal.tsx```

So adding vendors in `dashboard/src/config/providers/` never gets picked up, even with a force rebuild --no-cache

Also, although the Wizard will see the entries, if one add them in config/providers/  (and update the index.ts), and rebuild, the "add key" process will fail.
So the wizard is dynamic (after rebuild) (and I can add my ollama, lmstudio local references…) but the key page is not.

Am I mistaken or is it indeed an issue?
(not enough credits left to vibe code a fix, would love to push a PR)
