feat: 新增网卡配置文件生成器(ifcfg/NM keyfile/Netplan)

- 新增 3 个网络配置生成器,覆盖 CentOS/RHEL 7-9 + Ubuntu 18.04-24.04:
  - network-rhel-ifcfg: RHEL/CentOS 7-8 ifcfg 风格(network-scripts)
  - network-rhel-nmkeyfile: RHEL/CentOS 9 NetworkManager keyfile
  - network-ubuntu-netplan: Ubuntu Netplan YAML
- 每个生成器支持 5 种配置类型: 静态IP / DHCP / Bond / Bridge / VLAN
- Bond 支持 7 种模式(0-6),含 miimon/lacp_rate/成员网卡配置
- 支持路由 Metric 配置(ifcfg METRIC= / NM route-metric= / Netplan metric:)
- ConfigForm 增加 valueIn 依赖支持(修复 keepalived 已有但失效的 valueIn bug)
- 新增「网络配置」侧边栏分类,组件计数 60 -> 63
