feat: install shadcn-vue components for the portfolio + form surface

Adds button, card, input, textarea, label, select, form, sheet,
dialog, sonner, separator, aspect-ratio, dropdown-menu — the set
needed for the layout, project lightbox, and contact form.

Hoists baseUrl + paths into the root tsconfig.json so shadcn-vue's
CLI can resolve aliases (it reads the root config, not the app one).
Sets ignoreDeprecations="6.0" since TypeScript 6 warns about baseUrl
even though the CLI still requires it.
