feat: export admin page as a component and consume it in apps/admin

[paanSinghCoder]

Summary

• Moved the Admins (Super Admins) page from apps/admin/src/containers/super_admins/ to lib/admin/views/admins/ using git mv to preserve history.
• Exported AdminsView from @raystack/frontier/admin as a router-agnostic view (same behavior: list platform users + service users, client-side table, "Super Admins" header).
• Added a thin AdminsPage wrapper in apps/admin that renders <AdminsView />.
• Updated the super-admins route to use AdminsPage; route path and behavior unchanged.

Test plan

• Super Admins list loads with platform users and service users.
• Table sorting/filtering works (client-side).
• Organization link in table navigates to /organizations/:orgId.
• Lib build: pnpm build in web/lib.
• App build: pnpm build in web/apps/admin.

Resolve react-router-dom via Node resolution to avoid workspace layout coupling.

The hard-coded node_modules/react-router-dom path assumes a specific install layout; with pnpm's symlink-based resolution, this can be fragile across different setups. The similar vite config in web/apps/client-demo doesn't use this alias and resolves the package without issue—consider whether the alias is necessary. If it must be retained, use dynamic resolution (e.g., createRequire(...).resolve) instead of relying on a hard-coded path.

💡 Suggested fix (portable alias resolution)

import react from "@vitejs/plugin-react-swc";
import dotenv from "dotenv";
import path from "path";
import { fileURLToPath } from "url";
+import { createRequire } from "module";
import { defineConfig } from "vite";
import tsconfigPaths from "vite-tsconfig-paths";
import svgr from "vite-plugin-svgr";
dotenv.config();

const __dirname = path.dirname(fileURLToPath(import.meta.url));
+const require = createRequire(import.meta.url);
+const reactRouterDomPath = path.dirname(
+  require.resolve("react-router-dom/package.json")
+);

 resolve: {
   alias: {
-    "react-router-dom": path.resolve(__dirname, "node_modules/react-router-dom"),
+    "react-router-dom": reactRouterDomPath,
   },
 },
