fix(radio): restore the Radio QA harness and the row refresh it depended on (#736)

The harness called the compatibility facade's private _refreshTogglePanel,
which the layer-lifecycle refactor removed; Transit and Directions call
refreshLayerStats() on the bare lifecycle, which lacked it, so their rows
only repainted on the next tick. Add refreshLayerStats() to the lifecycle
and use it from the harness. With the crash gone, two further checks ran:
the selected-entity paint wait now also waits for Radio's own reveal, and
on phones the title bar sits 16 px from the top so both broadcast waves
stay on-screen.
