feat(map): packet flow - what the radio hears, as lines between nodes

Browse Source 
Every packet heard runs from its origin through the repeaters with a
position to this device; a packet sent is a ring. ui-core/PacketFlow.h
resolves them (UiCore::flow, MyMesh logRx/logTx -> Listener). ui-lvgl
draws them on the map's marker layer and repaints only their area while
they move; ui-new draws the last minute on the Nodes map ("Flow" in its
options). Setting: Map options > On the map > Packet flow, CLI map.flow.
Off by default. Sim-checked only.
