fix: map REVIEW_MAX_COMMENTS to both inline and context limits

REVIEW_MAX_COMMENTS was only mapped to REVIEW__MAX_INLINE_COMMENTS which
only limits comments per-file. Added REVIEW__MAX_CONTEXT_COMMENTS mapping
to also limit total comments per MR, which is what users expected.

Also added missing LLM__META__TEMPERATURE env var mapping.
