* docs: move deployment to beacon-docs and add SHOULDERS
* docs: keep only web-specific contributor notes
* docs: show the dev proxy settings needed for live updates
- node-types: new /stats/node-types endpoint + useNodeTypes; donutOption
replaces the "Coming soon" card with a live donut
- stats endpoints take iatas[] instead of a single iata, so multi-IATA
regions filter instead of falling back to all (drops useStatsIata)
- radio presets keep the node/observer split via stacked presetBarsOption
- drop client-side telemetry ms-normalization (backend now emits epoch ms
on both paths); charts pick delta-vs-raw counters off the response interval
- MeshTab: range-driven charts lead, all-time charts follow; KPI window
from overview.windowHours instead of a hardcoded 24h
- ci: docker-publish builds a :dev image on dev-branch pushes
