There is a problem with the implementation of the Agent begin-form:
although the enablePrologue switch and the prologue input box are hidden
in Task mode, these values are still saved in the form data. If the user
first enables the opening and sets the content in Conversational mode,
and then switches to Task mode, these values will still be saved and may
be used in some scenarios.

When calling HTTP to request data, if the JSON string returned by the
interface contains an unasked back slash like '\u', Python's RE module
will escape 'u' as Unicode, but there is no valid 4-digit hexadecimal
number at the end, so it will directly report an error. Error: re.

fix: preserve correct MIME & unify data URL handling for vision inputs
(relates #9248)

- Updated image2base64() to return a full data URL
(data:image/<fmt>;base64,...) with accurate MIME
- Removed hardcoded image/jpeg in Base._image_prompt(); pass through
data URLs and default raw base64 to image/png
- Set AnthropicCV._image_prompt() raw base64 media_type default to
image/png
- Ensures MIME type matches actual image content, fixing “cannot process
base64 image” errors on vLLM/OpenAI-compatible backends

### What problem does this PR solve?

This PR fixes a compatibility issue where base64-encoded images sent to
vision models (e.g., vLLM/OpenAI-compatible backends) were rejected due
to mismatched MIME type or incorrect decoding.
Previously, the backend:
- Always converted raw base64 into data:image/jpeg;base64,... even if
the actual content was PNG.
- In some cases, base64 decoding was attempted on the full data URL
string instead of the pure base64 part.
This caused errors like:
```
cannot process base64 image
failed to decode base64 string: illegal base64 data at input byte 0
```
by strict validators such as vLLM.
With this fix, the MIME type in the request now matches the actual image
content, and data URLs are correctly handled or passed through, ensuring
vision models can decode and process images reliably.
