### What problem does this PR solve?
Fix#6600
Hello, I have the same business requirement as #6600. My use case is:
We have many departments (> 20 now and increasing), and each department
has its own knowledge base. Because the agent workflow is the same, so I
want to change the knowledge base on the fly, instead of creating agents
for every department.
It now looks like this:

Knowledge bases can be selected from the dropdown, and passed through
the variables in the table. All selected knowledge bases are used for
retrieval.

Feat: Add user registration toggle feature. Added a user registration
toggle REGISTER_ENABLED in the settings and .env config file. The user
creation interface now checks the state of this toggle to control the
enabling and disabling of the user registration feature.
the front-end implementation is done, the registration button does not
appear if registration is not allowed. I did the actual tests on my
local server and it worked smoothly.
