[FEAT] add location sharing status to channel overview

[seh-len]

Please adjust the channel overview so that you can see at a glance which channel has activated location (>0) and for which channel (lowest index with activated location) automatic position updates are activated according to https://meshtastic.org/docs/configuration/tips/#sharing-location-on-a-private-secondary-channel.

Hi Yeraze,

thank you for the quick implementation.

I can now see the '📍' icon in the channels tab for the channel with automatic position updates.
But I don't see a separate icon for channels that also have location sharing enabled (precision > 0). In these channels, the location can still be requested manually.

In addition, I think it would be important if these parameters (location sharing enabled, automatic location sharing enabled) were also visible at a glance in the channel configuration in the device tab.

The meshtastic android app, for example, also allows channels to be reordered to swap primary and secondary. I have not been able to do this in meshmonitor so far. I can make the primary channel secondary, but changing the secondary channel to primary is confirmed but has no effect.

Thank you very much.

Kind regards,
Simon

Thanks, that's exactly how I thought it would be. ❤️
