feat(HEL-850): disable thinking for translate/polish via reasoning_effort none

LM Studio's OpenAI-compat endpoint silently ignores chat_template_kwargs
(probed live); reasoning_effort "none" verifiably removes reasoning tokens
on both streaming and blocking paths. Pass it through the existing
LLMClient extra_body channel for translate/polish first and correction
requests only; all other callers keep their default policy.
