fix(diarization-ui): validate non-empty content before LLM call, add OLLAMA_THINK flag

Empty documents caused the model to spin in its thinking loop and waste
all tokens. Now raises a clear job error before the Ollama call.
Also adds OLLAMA_THINK env var (default false) to control whether
the model uses extended thinking - disabling it avoids runaway thinking
loops on ambiguous inputs.
