Add a new trace span in doAccept() capturing ledger close time details:
- xrpl.consensus.close_time: agreed-upon close time (epoch seconds)
- xrpl.consensus.close_time_correct: whether validators converged
(per avCT_CONSENSUS_PCT = 75% threshold)
- xrpl.consensus.close_resolution_ms: time rounding granularity
- xrpl.consensus.state: "finished" or "moved_on" (consensus failure)
- xrpl.consensus.proposing: whether this node was proposing
Update Tempo datasource with close time filters, plan docs with
new span inventory, and add test coverage for the attribute pattern.
