PropagationGridWorker now broadcasts a {:propagation_pipeline_progress,
%{forecast_hour:, valid_time:}} message on the propagation:pipeline
PubSub topic at the start of each process_forecast_hour/4 call.
MapLive subscribes on mount, stashes the last message in the new
:pipeline_progress assign, and clears it on the refresh tick whenever
PipelineStatus flips out of :running.
The chip component consults a new PipelineStatus.running_label/1
helper that formats the payload as "Updating propagation · now" for
f00 and "Updating propagation · +Nh" for f01-f18, falling back to
the base running label until the first progress message arrives.
Covered by unit tests on the formatter and an integration test in
MapLiveTest that seeds an executing grid job, broadcasts progress,
and asserts the rendered chip.
The running label "Updating propagation (HRRR run)" didn't fit in
the 224 px desktop sidebar alongside the NTMS title block, so it
was being truncated. Move the chip to the bottom of the sidebar
(below the auth menu) where it can use the full sidebar width,
let the text wrap naturally instead of truncating, and drop the
trailing ellipsis. Mobile chip stays at the top since the mobile
layout collapses menu + auth into a dropdown.
Adds a small chip below the NTMS title in both the mobile and
desktop sidebars of /map that collapses PropagationGridWorker +
AsosAdjustmentWorker Oban state into one of four states —
running / idle / stale / unknown — with a plain-language label
("Updating propagation (HRRR run)…", "Up to date · 12m ago").
The chip refreshes on a 15s timer and whenever the pipeline
broadcasts propagation:updated, so a long HRRR sweep is visible
from the moment a visitor opens the page.
