[add] REST Table component based on Shadcn UI

[Copilot]

Implements RestTable component following the MobX-RESTful-table architecture but using Shadcn UI instead of Bootstrap. Updates README with component documentation and usage patterns.

Changes

RestTable Component (registry/new-york/blocks/rest-table/)

• Full CRUD table with MobX RESTful integration
• Multi-select via checkbox column
• Custom column renderers (URL, email, file, badge lists)
• Filter bar via RestForm, pagination via Pager
• Loading states with spinner

<RestTable
  editable
  deletable
  columns={[
    {
      key: "name",
      renderHead: "Repository",
      renderBody: ({ html_url, name }) => (
        <a href={html_url}>{name}</a>
      ),
    },
    { key: "language", renderHead: "Language" },
    { key: "stargazers_count", type: "number", renderHead: "Stars" },
  ]}
  store={repositoryStore}
  translator={i18n}
  onCheck={console.log}
/>
