API options like `stream` was ignored when no session_id was provided.
This PR fixes the issue.
Test command and expected result:

Fix: Use self.dataStore.indexExist in all_tags method of Dealer (#5108)
### What problem does this PR solve?
This PR fixes an AttributeError in the all_tags method of the Dealer
class. Previously, the method incorrectly called
self.docStoreConn.indexExist instead of self.dataStore.indexExist. Since
self.docStoreConn was never set (and self.dataStore is already
initialized in init), this resulted in an error when attempting to check
if the index exists. This change ensures that the proper connector is
used for the index existence check, thereby resolving the issue._

Fix: PUT method does not work as expected with Invoke component (#5081)
### What problem does this PR solve?
Invoke component can be used to call third party services.
Tried GET/POST/PUT from web UI, and found PUT request failed like this:
(test api: api/v1/chats/<assistant_id>)
```
{"code":100,"data":null,"message":"AttributeError("'NoneType' object has
no attribute 'get'")"}
```
Root cause: Invoke PUT with a 'data=args' parameter, which is a form-encoded data, however the default content type setting of request header is application/json. The test api could not deal with such case.
Fix: use the 'json' parameter of reqeusts.put(), same as Invoke POST. Do not use the 'data' parameter.
Another way is to use 'data=json.dumps(args)'.

### What problem does this PR solve?
The current design is not well-suited for multimodal models, as each
model can only be configured for a single purpose—either chat or
Img2txt. To work around this limitation, we use model aliases such as
gpt-4o-mini and gpt-4o-mini-2024-07-18.
To fix this, this PR allows specifying the Img2txt model by tag instead
of model_type.

Update agent session API, to support uploading files while create a new session (#5039)
### What problem does this PR solve?
Update the agent session API "POST /api/v1/agents/{agent_id}/sessions",
to support uploading files while create a new session:
- currently, the API only supports requesting with a json body. If user
wants to upload a doc or image when create session, like what is already
supported on the web client, we need to update the API.
- if upload an image, ragflow will call image2text, and a user_id is
needed for the image2text model. So we need to send user_id in the API
request. As form-data is needed to upload files, not json body, seems we
need to put the user_id in the url as an optional parameter (currently
user_id is an optional in json body).

Fixes KeyError: 'content' when using stream=False (#4944)
### 🛠 Fixes `KeyError: 'content'` when using `stream=False`
#### 🔍 Problem
When calling the chat API with `stream=False`, the code attempts to
access `msg[-1]["content"]` without verifying if the key exists. This
causes a `KeyError` when the message structure does not contain
`"content"`.
This issue was discussed in
[#4885](https://github.com/infiniflow/ragflow/issues/4885), where we
analyzed the root cause. The error does not occur with `stream=True`, as
the response is processed differently.
#### ✅ Solution
- **Logging Fix:**
- Before accessing `msg[-1]["content"]`, we check if the key exists.
- If it does not exist, a default value (`"[content not available]"`) is
used to prevent errors.
- **Structural Fix in `msg` Construction:**
- Ensured that every message in `msg` contains the `"content"` key, even
if empty.
- This fixes the issue at its root and ensures consistent behavior
between `stream=True` and `stream=False`.
#### 🔄 Impact
- Prevents the `KeyError` without affecting normal application flow.
- Ensures the integrity of the `msg` structure, avoiding future
failures.
