fix: stabilize traceroute map node identity & fix log metric alignment

[jamesarich]

Why

Two related bugs in the traceroute UI/rendering path, grouped because they live in the same view and are cheap to fix together.

🐛 #6197 — Traceroute map node IDs change on every reload

On the traceroute map, node markers show the wrong IDs, and re-opening the same traceroute shuffles them. The google-flavor marker loop in TracerouteMapContent emitted MarkerComposables positionally with no composition key and no MarkerComposable keys:

displayNodes.forEach { node ->
    val markerState = rememberUpdatedMarkerState(position = node.position.toLatLng())
    MarkerComposable(state = markerState, zIndex = 4f) { NodeChip(node = node) }
}

displayNodes is derived from a live, time-sorted node flow, so its order is not stable between reloads. MarkerComposable caches its rendered icon bitmap keyed by its keys vararg (empty here), and Compose reuses marker slots positionally — so when the list reorders, a marker keeps a stale cached chip while getting a different node's position, making node IDs look wrong and unstable. This is the same unstable-key class of bug seen elsewhere in the app (lists keyed on index/timestamp instead of node.num).

Fix: wrap each marker in key(node.num) and pass node.num + short_name as MarkerComposable keys, so each marker's composition state and cached bitmap stay bound to its stable node identity. This mirrors the existing NodeTrackMap marker pattern, which already wraps markers in key(position.time).

🐛 #5743 — Traceroute log metric alignment

In the Traceroute Logs list, the third metric label (round-trip time) was crushed and wrapped one character per line vertically. The metrics sat in a plain Row with three items that can't fit the narrow card — worse with longer translated strings (reported in Russian, also reproduces on desktop and in English).

Fix: use FlowRow so the metrics wrap onto a new line cleanly instead of the last item being squeezed to zero width.

Testing Performed

• ./gradlew spotlessApply spotlessCheck detekt — clean, no violations
• ./gradlew assembleDebug — passes (all flavors)
• ./gradlew :feature:node:allTests — passes (~130 tests)

Marker keying is a Compose-recomposition fix that isn't covered by the existing headless tests; the node-selection resolution (tracerouteNodeSelection, already num-keyed) remains covered by TracerouteNodeSelectionTest.

Closes #6197
Closes #5743

Summary by CodeRabbit

• Bug Fixes
  • Improved traceroute map marker stability so hop markers keep the correct node details when the list updates or reorders.
• UI Improvements
  • Enhanced traceroute metrics layout to wrap onto multiple lines on smaller screens, improving readability when labels don’t fit horizontally.

📝 Walkthrough

Walkthrough

Traceroute map markers now use stable Compose keys tied to node identity and receive node metadata inputs. Traceroute log metrics now use a wrapping FlowRow with configured horizontal and vertical spacing.

Changes

Traceroute UI

Layer / File(s)	Summary
Stable traceroute map markers androidApp/src/google/kotlin/org/meshtastic/app/map/MapView.kt	Traceroute node markers and their chip composition state are keyed by node number, while marker metadata is passed through composition inputs.
Wrapping traceroute metrics feature/node/src/commonMain/kotlin/org/meshtastic/feature/node/metrics/TracerouteLog.kt	TracerouteCardMetrics uses FlowRow with full-width layout and explicit spacing so metric labels can wrap onto additional lines.

MarkerComposable to include node.colors and node.isIgnored in addition to
node.num and node.user.short_name, ensuring the marker recomposes when any
NodeChip input changes while preserving the stable node identity.
