Two live-verified dashboard defects found while auditing the devnet nodes. Sub-millisecond spanmetrics buckets. The ladder started at 1ms, but most xrpld spans are far below that: tx.preflight means ~0.012ms and tx.preclaim ~0.15ms. On the live nodes the first bucket held 13,761,009 of 13,761,419 tx.preflight samples (99.997%), so histogram_quantile pinned every p95/p99 at a constant 0.95ms and ~10 latency panels reported a boundary artifact rather than a measurement. Adds 0.01/0.05/0.1/0.25/0.5ms ahead of 1ms in all three bucket lists, which must stay identical or the connector misbuckets. consensus_mode filter on spans that never carry the label. Only consensus.round and consensus.ledger_close are stamped with consensus_mode (verified against live series), so panels 1, 3, 12 and 14 -- which query consensus.validation.send, consensus.proposal.send and consensus.accept.apply -- blanked as soon as an operator picked any value from the Consensus Mode dropdown. Drops the selector from those four; ids 2 and 11 keep it because their spans do carry it. Note: existing histogram series retain the old le boundaries, so span-latency panels show a discontinuity at collector restart.
