fix(ts-oss): honor LMSTUDIO_BASE_URL env var in LM Studio LLM and embedder

Both the TS OSS LM Studio LLM and embedder hardcoded the base URL default
without checking the LMSTUDIO_BASE_URL environment variable, unlike the
Together provider which already supports TOGETHER_API_BASE. Precedence is
now explicit config value > LMSTUDIO_BASE_URL env var > existing default.
