Add admin dashboard data loading & package dependencies

Removed 'admin-header.tsx' and 'admin-sidebar.tsx' components and added 'admin-dashboard.loader.ts' to handle loading data for the admin dashboard. Updated 'admin-dashboard.tsx' and 'page.tsx' to use this loader. Package dependencies were also updated in 'pnpm-lock.yaml' and 'package.json' files of relevant packages. This commit prioritizes loading dashboard data effectively and managing package dependencies.
