Cardano Updates

Replace locally-defined orphan `ToJSON`/`FromJSON` instances that
already exist in `Cardano.Network.OrphanInstances` (from the
`cardano-diffusion:orphan-instances` sublibrary) with imports of that
module:

- `TopologyP2P`: remove `FromJSON/ToJSON PeerTrustable`,
  `FromJSON/ToJSON (NetworkTopology UseBootstrapPeers PeerTrustable)`,
  and `FromJSON UseBootstrapPeers`; add `Cardano.Network.OrphanInstances ()`
  and `Ouroboros.Network.OrphanInstances ()` imports.

- `StateRep`: remove local `ToJSON/FromJSON NodeToNodeVersion`,
  `ToJSON/FromJSON NodeToClientVersion`, and `parseBoundedEnum`; add
  `Cardano.Network.OrphanInstances ()` import.

- `Tracers`: remove Show-based `ToJSON NodeToNodeVersionData` and
  `ToJSON NodeToClientVersionData` stubs; add
  `Cardano.Network.OrphanInstances ()` import.

Additionally fix two pre-existing issues in `Consensus.hs`:

- `deltaq`: use `toJSON gsv` (structured JSON via
  `Ouroboros.Network.OrphanInstances`) instead of `String . show`.

- `TraceDecisionEvent`: restore the `dtal >= DMaximum` conditional
  branch (replacing the reversed fold), using `forMachine DMaximum`
  for the verbose case.

In `Startup.hs`, fix `ConsensusNetworkVersionTuple` to emit proper
structured JSON for `nodeToClientVersion`/`nodeToNodeVersion` via
`ToJSON` from `Cardano.Network.OrphanInstances`, and fix the
`maxNodeToNode/ClientVersion` field to show only the version key
rather than the full `(key, value)` pair.

- Acceptors/Utils.hs: include node_name alongside node_id in SeriesIdentifier
- Component.hs: generalise insert to accept SeriesIdentifier directly; fix
  pruning period default (was 3600 ms ≈ 3.6 s, now 15 min)
- Component/Trace.hs: update TimeseriesTraceInsert to carry SeriesIdentifier;
  emit query_text/query_result only at DDetailed; lower Prune severity to Debug
- TimeseriesServer.hs: rename node/state → node/sync-progress; remove #if RTVIEW
  guard (endpoint is now unconditionally available); return JSON objects from
  GET config/retention and GET config/pruning instead of plain text
- Utils.hs: move NodeStateWrapper (and its FromJSON instance) here from
  RTView/Update/NodeState.hs so it can be shared without the RTVIEW flag;
  move vector from rtview-only to unconditional build-depends
- RTView/Update/NodeState.hs: remove NodeStateWrapper definition (now in Utils)
- grafana-datasource: rename node-state → node-sync-progress throughout
  (QueryEditor, datasource, types, dashboard); rename dashboard to rtview-port
- grafana-datasource: add README with build and run instructions

Addresses all review comments from PR #6580 (mgmeier). The root cause of
most issues was that `Cardano.Tracing.HasIssuer` was incorrectly deleted
as part of the iohk-monitoring cleanup
