Adds a visibility-aware 30s poll on the Routing tab so the graph reflects
tunnel state, alias publishes, and remote-node disconnects without a
manual reload. Polling pauses while the tab is hidden and wakes
immediately on focus via the shared visibilityInterval helper.
Tightens nodeStateEqual so a stack swap on the same node (opt out A, opt
in B) is detected even when the count is unchanged. Extracts the helper,
the minimap colour mapping, and the minimap colour literals to
mesh-topology-layout so they can be unit-tested and to drop a now-unused
isOwnerView field from MeshNodeData.
Persists the Table/Graph and Tunnels/Aliases toggles to localStorage so a
Routing tab session keeps the operator's last-used view.
Adds a legend line to the per-stack topology sheet clarifying that
consumer edges mean meshed peers that could reach the aliases via DNS;
whether containers dial them depends on each consumer's own opt-in
stacks.
Adds unit tests for stacksKey, meshNodeStateEqual, and miniMapColorFor,
plus troubleshooting entries and a refresh-cadence note to the mesh docs.
Adds a Table/Graph toggle to Fleet → Traffic. Graph mode draws the fleet
as a ReactFlow diagram with a second toggle that switches edge encoding
between Tunnels (one edge per node pair, coloured by tunnel state) and
Aliases (same edges labelled with alias counts). Clicking a node card
opens the existing opt-in sheet, where each opted-in stack now has a
Topology button that opens a focused side sheet showing the stack at
the centre, the aliases it publishes, and the meshed consumer nodes
with per-tunnel state.
Reuses the existing /mesh/status and /mesh/aliases endpoints; no
backend changes. Inherits the Admiral gate from the parent Routing
tab. Layout helpers and the per-stack sheet are unit-tested.
