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.
