docs: correct the modpack feature claim — approval auto-builds; deployment is...

- **备份与恢复**：一键把整服数据（世界、配置、插件/模组，即整个 /data 卷）打包进集群内的归档库，支持从任意备份点回滚；默认安装就已启用（归档 PVC 与路径由安装器一并生成）。

- **智慧回收（可选开启）**：超过 15 天无人游玩的世界自动备份后删除，释放磁盘空间；安装时设置 `FELIS_WORLDS_HOST_PATH`（k3s 默认 `/var/lib/rancher/k3s/storage`）即启用每日回收，不设置则不删任何世界。

- **多核心支持**：兼容 Paper、Fabric、Forge、NeoForge，经由 Velocity 代理统一入口。

- **模组自助提交**：玩家自行上传模组包，服主审批通过后自动构建并部署。

- **模组自助提交**：玩家自行上传模组包，服主审批通过后自动构建；构建产物进入镜像白名单，可直接选用为服务器镜像完成部署。

- **Passkey 登录**：支持指纹、面容、硬件密钥等无密码认证方式。

- **零信任安全**：面板流量由 Cloudflare Access 保护，集群内 API 不暴露到公网。

- **Backup & Restore**: One-click snapshots of a server's whole data volume (worlds, config, plugins/mods — the entire /data volume) into the cluster's archive store, with rollback from any backup point — enabled by default (the installer renders the archive PVC and its path).

- **World Reaper** (opt in): Worlds idle for more than 15 days are automatically backed up and removed to free disk space. Enable it by setting `FELIS_WORLDS_HOST_PATH` at install time (on k3s: `/var/lib/rancher/k3s/storage`); without it, no world is ever deleted.

- **Multi-core Support**: Compatible with Paper, Fabric, Forge, and NeoForge, federated behind a Velocity proxy.

- **Modpack Submission**: Players submit custom modpacks; admin approval triggers automatic build and deployment.

- **Modpack Submission**: Players submit custom modpacks; admin approval triggers an automatic build, and the result is whitelisted as a server image you can select to deploy.

- **Passkey Login**: Passwordless authentication via fingerprint, face recognition, or hardware security keys.

- **Zero Trust Security**: Panel traffic protected by Cloudflare Access; the internal API is never exposed to the internet.
