refactor(settings): move unknown-base-model routing to Library > Folder Settings

The setting decides which library an unknown-model download lands in, so
it belongs next to the default-root selects rather than General >
Downloads. Element id, settings key and i18n keys are unchanged, and
loadSettingsToUI() populates it by getElementById on every modal open,
so no JS changes are needed.

Also drop "(recommended)" from the diffusion-models option label; the
default is already conveyed by pre-selection.
