Subject: [PATCH] test(layoutStore): silence expected warn in invalid-JSON case

The "defaults to list mode when localStorage has invalid data" test feeds
invalid JSON on purpose; createPersistentStore logs and swallows the parse
error, so its warning (with stack) was polluting CI output. Spy on
console.warn to silence it and assert it fired, matching the equivalent
test in createPersistentStore.test.ts.
