不应覆盖原有form上传逻辑，分片上传和原form应作为两种上传方式供用户选择

二选一：
- 应在服务端生成upload_id
- 服务端应校验upload_id与首个分片的哈希值是否一致，同时在首个分片上传成功前拒绝其它分片

Description / 描述
This PR implements the frontend logic for chunked file uploads in form mode, corresponding to the backend changes.
此 PR 实现了 Form 模式下分片上传的前端逻辑，以配合后端的变更。
Key changes include:
主要更改包括：
文件切片：实现了上传前根据后台配置对文件进行切片的逻辑。
crc-32calculation for each chunk to ensure data integrity during transmission.完整性校验：为每个分片添加了
crc-32计算，以确保传输过程中的数据完整性。上传循环：更新了上传组件以处理分片的顺序上传和错误重试。
Motivation and Context / 背景
Standard form uploads are prone to failure with large files or unstable network conditions. Introducing chunked uploads improves reliability and user experience.
普通的表单上传在处理大文件或网络不稳定时容易失败。引入分片上传可以显著提高可靠性和用户体验。
Relates to OpenListTeam/OpenList#1928
How Has This Been Tested? / 测试
手动测试了 Form 模式下上传大于 500MB 的大文件。
crc-32is correctly calculating checksums for chunks.验证了
crc-32能正确计算分片的校验和。验证了配合后端 (PR #1928) 能成功合并文件。
