chore: add Storybook 10 setup with PrimeVue + Tailwind integration

Installs Storybook 10.4 in apps/app/ as a component-development and
autodoc tool. Configures viteFinal with all seven SPA aliases so
stories resolve imports identically to the dev/build pipeline.
preview.ts reuses @/plugins/primevue's installPrimeVue() so Storybook
stays in lock-step with main.ts whenever the PrimeVue config changes.

Only the addons we need are wired: addon-docs (autodocs) and
addon-a11y (axe-core checks). addon-interactions is intentionally
omitted — interaction testing stays in Playwright CT per the testing
architecture.

Seed stories: PrimeVue Button (Primary/Secondary/Danger), Tailwind
utility box, and FormField (Default/WithError/Disabled) wrapped in
@primevue/forms Form + Zod resolver.

Adds make storybook target alongside make app / make docs.
