Attempt list endpoints always read event data, event metadata and response data from the log store, then drop them unless include asks for them. These can be the largest columns in an attempt row, so a list without include loads payloads that never reach the response. Attempt list reads now take the payload fields to read: the handler asks only for what include needs, and the stores skip the rest. Responses are unchanged for every include combination.

Changes

1. ListAttemptRequest.Include lists the payload fields to read (event.data, event.metadata, response_data). Nil reads none of them; callers that need the full record pass AllFields.
2. The attempt list handler sets Include from include: event.data reads event data, event or event.data reads event metadata, response_data reads response data.
3. The manual retry lookup, the scheduled retry lookup and the ClickHouse ListLatestAttempts fallback pass AllFields, so retries still deliver the full event; tests on both retry lookups fail if they stop asking.
4. ClickHouse and Postgres select an empty value in place of a column that wasn't asked for; the in-memory store clears those fields.
