Milvus-adapter cognee version update to support new API endpoints

[prasanjit101]

The current adapter doesn't support new API endpoint i.e., AttributeError: module 'cognee' has no attribute 'remember'
Currently, it is using cognee==0.5.6
And is not updated to be used with the latest version of Cognee 1.1.0
And is thus breaking.

Hi, I'd like to work on this issue. I'm new to open source but have experience with vector DBs (ChromaDB, RAG pipelines). Can I take this?

I was able to reproduce the issue locally on window 11, Python3.13, cognee 1.2.1.
Here are the Bugs that i found:-
1> Multiuser access control conflict
Milvus is not registered as a supported handler in cognee 1.0's new access control system.

2> Async event loop conflict
get_milvus_client() uses loop.run_until_complete() inside an already running async context.

Right now working on these issue to solve it.
