Chart captions now draw through axis_caption, so a wide volume/SNR/day
chart gains quarter/mid time marks between its edge labels. Nodes whose
stored observations never carried a name ask the device's contact list
before rendering as "unknown" (picker and arrivals alike), and the hash
lanes go through the shared hash widget. make_node_resolver learns an
optional stored-names fallback and the repository can serve the latest
advertised name per node, for the dashboard feed to use next.
