Add second LTE channel to real time WAN quality graphs, actual band numbers below

When in a new location I’ll drive around and my partner will be checking RSRP/SINR for two carriers on the real time WAN quality page. While this works well if cellmapper isn’t accurate for the area I’m in (I’ll sometimes be staring right at a tower that doesn’t exist on it), there are some issues:

  • current values are only readable if you are clicking on the graph. it’d be nice to have a readout below them ala band / secondary band in wan connection status.

  • add in a second graph for the second channel connected (if any). sometimes this is stronger than the primary channel, and at the very least it gives a more complete picture of what’s happening.
