feat: 优化网络绑定配置支持外部访问

主要修改点：
1. 网络绑定调整
   - .env.example: WEB_HOST/VITE_WEB_HOST 从 127.0.0.1 改为 0.0.0.0
   - server/src/app/core/config.py: 默认 web_host 从 127.0.0.1 改为 0.0.0.0
   - web/package.json: Vite 脚本 host 从 127.0.0.1 改为 0.0.0.0
   - web/vite.config.js: normalizeState 中 WEB_HOST 默认值从 127.0.0.1 改为 0.0.0.0

2. CORS 配置扩展
   - .env.example: CORS_ORIGINS 添加 http://0.0.0.0:5173

3. Shell 脚本权限修复
   - server/start.sh, start.sh: 添加可执行权限 (644 -> 755)

4. Setup 表单与验证逻辑简化
   - web/src/composables/useSetupView.js:
     - 新增 readCurrentWebEndpoint() 从 window.location 自动检测当前 web host/port
     - 简化 runtimeInputsReady: 移除 web_host/web_port 必填验证，仅保留 server_host/server_port
     - 简化 buildRuntimeFingerprint(): 移除 web_host/web_port
     - buildPayload() 改用 readCurrentWebEndpoint() 解析 web 配置
   - web/vite.config.js:
     - 新增 resolveRuntimePayload(): 运行时解析 web_host/web_port
     - 移除 validateRuntimePayload() 中的 web_host/web_port 字段验证
     - 移除 testRuntimePorts() 中 web 端口冲突检测逻辑
     - 移除 canReuseCurrentWebPort() 函数

5. CSS 清理
   - web/src/assets/styles/views/setup-view.css: 移除未使用的 .setup-summary-grid 和 .setup-summary-item 样式
