ScopeBanner (the UI surface)

One severity-styled ScopeBanner component renders every scope note the backend returns — refuse as a hard error, blocking as a red banner that also disables the datasheet button, warn as orange, info as blue — replacing what used to be several scattered, inconsistent honesty signals across different endpoints.

• You're building a new UI surface (a new panel, a new result view) that needs to show solver honesty notes and want the one correct pattern to reuse.
• A blocking note fired but you don't see a banner on screen — that's a wiring bug, not a solver bug.
• You want to confirm end-to-end that a backend note actually reaches the screen, not just the API response.

Consumes a single structured scope[] array plus a has_blocking boolean from the API response and maps severity to banner colour/behaviour in one place, so every new endpoint that returns scope notes gets consistent UI for free instead of a bespoke render.
