Expand the capabilities of the MCP Server. #8644.

Special thanks to @Drasek, this change is largely based on his original
implementation, it is super neat and well-structured to me. I basically
just integrated his code into the codebase with minimal modifications.

My main contribution is implementing a proper cache layer for dataset
and document metadata, using the LRU strategy with a 300s ± random 30s
TTL. The original code did not actually perform caching.

### What problem does this PR solve?

When the `dataset_ids` parameter is omitted in the **update assistant**
request, Passing an empty array `[]` triggers a misleading
message"Dataset use different embedding models", while omitting the
field does not.
To fix this, we:
- Provide a default empty list: `ids = req.get("dataset_ids", [])`.  
- Replace the `is not None` check with a truthy check: `if ids:`.

**Files changed**  
`api/apps/sdk/chat.py`  
- L153: `ids = req.get("dataset_ids")` → `ids = req.get("dataset_ids",
[])`
- L156: `if ids is not None:` → `if ids:`
