fix(nitro): Preserve debug IDs and source maps when disable-upload is set

When `sourcemaps.disable` is `'disable-upload'`, the plugin should still
inject debug IDs and keep `.map` files so users can upload them manually.
Previously, both `injectDebugIds()` and `deleteArtifacts()` were
incorrectly gated or ungated, causing debug IDs to be skipped and source
maps to be deleted even in the manual-upload workflow.
