chore: Add Next.js project config and app entry for admin-web
The previous deploy.sh commit included Dockerfile and docker-compose
but was missing the actual Next.js project files needed for `npm ci`
and `npm run build` to succeed. This adds the complete project skeleton.
## Project configuration files
### package.json
- Next.js 15.1.11, React 18, TypeScript 5.9
- Dependencies: @reduxjs/toolkit, @tanstack/react-query,
@tanstack/react-table, axios, recharts, zustand, dayjs, clsx
- Scripts: dev, build, start, lint, format, type-check
### next.config.ts
- output: 'standalone' — required for Docker multi-stage build
- / redirects to /dashboard
- Remote image patterns enabled
### tsconfig.json
- Strict mode, bundler module resolution
- Path alias: @/* → ./src/*
- Incremental compilation enabled
### .gitignore / .dockerignore
- Standard Next.js ignores (node_modules, .next, out, coverage)
- Docker build excludes dev files, docs, git, IDE configs
## App Router entry files
