perf(monitoring): exclude payloads from session summaries

Exclude message_content and variables from the message source used by conversation session summaries. These fields were carried through window sorting even though the resulting summaries did not use them. Preserve complete payloads for message detail queries. Add regression coverage for summary counts, session metadata, and full message retrieval.
