Constrain admin table to plain HTML (no missing shadcn import), fix install-timeout silently passing as success

 - Framer Motion for animation
 - Server Components by default — only add "use client" to a file that genuinely needs interactivity, state, or animation hooks
 
+AVAILABLE shadcn/ui COMPONENTS — the scaffold only includes these under components/ui/: button, card, badge, avatar, separator. Do NOT import from "@/components/ui/{anything else}" (table, dialog, tabs, select, dropdown-menu, etc.) — they do not exist in this project and WILL break the build. For the admin data table specifically: build it with plain semantic HTML — <table>, <thead>, <tbody>, <tr>, <th>, <td> — styled directly with Tailwind utility classes (border-collapse, divide-y, divide-border, text-sm, etc.). Do not import any table component.

 FILES YOU MUST NOT GENERATE (already provided by the project scaffold — generating them will conflict):
 package.json, tsconfig.json, next.config.ts, postcss.config.mjs, tailwind.config.ts, next-env.d.ts, .gitignore, any file under components/ui/, lib/utils.ts
