fix: system prompt ignored in unsloth inference (#4528)
* fix: system prompt was dropped in unsloth text and vision inference

* refactor: simplify system prompt message construction

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* fix: use multimodal typed content parts for vision system message and add fallback

The system message content must use typed content parts
([{"type": "text", "text": ...}]) instead of a plain string to match
the multimodal processor contract (consistent with the audio path).
Plain strings cause some processors (e.g. LLaVA) to silently drop the
system prompt.

Also wraps processor.apply_chat_template in try/except so models that
reject the system role gracefully fall back to no system message with
a warning log.
