Some Hugging Face backends (e.g. Featherless AI) only route requests
if the user has added their own API key for that provider at HF's
settings — surfaced by Confab as a bare "not supported by any
provider you have enabled" error with no indication why. Enriches
that specific error with guidance, and adds the same note to the
Custom Model ID entry point. Also converted the alert-based Custom
Model ID dialog to a real sheet since SwiftUI alerts can't be resized
and it read as cramped.
