test(canvas): add explicit STATUS_CONFIG shape coverage

STATUS_CONFIG exports 7 status keys (online, offline, paused, degraded,
failed, provisioning, not_configured) with dot/glow/label/bar per entry.
The existing statusDotClass.test.ts covered .dot indirectly but left the
constant's full shape (label, glow, bar) untested. Add a dedicated
design-tokens.test.ts that asserts all keys exist, every entry has the
correct fields, and field values match the known tailwind tokens.

-// @vitest-environment jsdom

-// Behavioral coverage for the SkillsTab registry loading and source schemes
-// flows. Two regressions this pins down:
-//
-//  1. Registry fetch timeout: when GET /plugins takes >10s the component
-//     used to silently swallow the error (console.warn only), making it
-//     indistinguishable from a genuinely empty registry. Now it surfaces
-//     a specific timeout error with a Retry button so the user can recover.
-//
-//  2. Source schemes fallback: GET /plugins/sources failure is silent
-//     (falls back to "local only" UX) rather than crashing the component.
-//     This test verifies the fallback works without breaking the rest of
-//     the UI.
