The config dialog reads each widget kind's schema from the static frontend
SERVICE_REGISTRY (registry.ts), not the backend pydantic schema. The previous
commit added unit/scale to the backend configs but not to the frontend mirror,
so the options never appeared in the dialog — the Prometheus "chart" binding
still listed only promql/window and the qBittorrent "speed" binding had an
empty configSchema.
Add a shared AXIS_FORMAT_PROPERTIES fragment (unit + scale enums) and spread
it into the prometheus chart and qbittorrent speed bindings, with matching
defaultConfig (chart: none/auto; speed: bytes_per_sec/auto). Combined with the
enum <Select> rendering already added to WidgetConfigDialog, the options now
show up as dropdowns when editing those widgets.
Test: registry exposes unit/scale enums on chart + speed; speed defaults to
bytes_per_sec. 180/180 frontend tests pass; tsc + ESLint clean.
