Subject: [PATCH] feat(mesh): RSSI/SNR dBm tooltip on the existing signal-bars
 indicator

The bars UI (signalBars/.mesh-signal-bars) was already built and wired to
mp.primary_rssi -- it just needed real backend data, which the previous
commit provides. Adds primary_snr alongside primary_rssi in MergedPeer and a
hover tooltip showing exact dBm/SNR values.
