Drop the cursor-following hover tooltips from the masthead stat tiles: the RUNNING
tile on the Home dashboard (the managed / external / exited breakdown) and the
CONTAINERS tile on the Fleet view (the running / total split). Both revert to plain
stat tiles, matching the CPU and MEM tiles beside them. The dashboard and fleet docs
are updated to match and the orphaned screenshot is removed.
Introduce a status masthead above the node grid summarising fleet-wide
CPU, memory, container, and alert counts with a coloured rail that
reflects overall health. Pin the local node at the top of the grid with
a cyan accent rail and a Local badge so it is never confused with a
remote. Add a Topology view toggle that plots the local node on the
left with remotes radiating out, and colour-codes connector lines by
link health.
