[🚧 Fix] <PLS & FS> Improve PLS download logic & UX

1. [+] 增加了 PLS 下载操作的取消功能
2. [/] 修复了 FS IPC 中 `downloadFile` 时, 过早地从 downloadTasks 中删除任务的逻辑错误。
3. [↑] 改进了 PLS IPC 中 `handlePLSDownload` 获取版本信息时的逻辑, 现在该函数会从全局 API 信息中逐个尝试 API 域名。减少了极端网络环境下, 版本信息获取失败的可能性。
4. [/] 修复了下载失败后, 下载按钮依然保持灰显的问题。
5. [+] 为 PLS 下载增加了进度条显示。
6. [/] 优化了 `plsConnectionManager` 中一些不必要的 IPC 状态同步 (有些时候还会导致逻辑错误)。
