Feature Request: Add support for Open WebUI

[working-name]

Hello!

Can you please add another config item apiKey for Open WebUI? It basically forwards the backend ollama API but takes an Authorization: Bearer sk-api-key-here header. Maybe here?

Open WebUi's docs about continue.dev integration.

NOTE http:// prefix seems to be hardcoded, maybe let that part be specified in the plugin's settings, the URL? If you run open webui behind nginx or something with an SSL cert ...

NOTE2 With your current plugin's setup, after removing the hardcoded http://, the endpoint would be https://my.openwebui.com/ollama, since you're appending /api/generate

Thanks!
