fix(storybook): glob all package stories + declare core-ui dep

The stories glob covered only packages/core-ui, so any feature story a
component-must-have-story fix produces would be invisible in Storybook
and skipped by pnpm test:stories. Glob every package's src tree and
declare the workspace dep on @repo/core-ui (the only storied package
today) so turbo's build cache invalidates when its stories change.
Verified: storybook build succeeds, 18 stories in index.json. (S7)
