What problem does this PR solve?

My business team wants to use file management like a cloud storage service, but the current file management system is quite cumbersome. It requires managing a knowledge base, then finding documents in the knowledge base to parse them. Therefore, I have simplified the steps, but I am not sure if this is what most people need.

Type of change

• After creating a folder and managing the knowledge base, record this relationship. Any files uploaded or subfolders created under this folder will be associated with this knowledge base
• When uploading files to a folder associated with a knowledge base, you can check 'Parse on creation', which will automatically enable parsing without needing to jump to the knowledge base page to find the document
• When modifying the associated knowledge base of a folder, all nested files below will also be modified: documents will be created in the new knowledge base and deleted from the old knowledge base.
