[Feature request] Improve interfacing of alarms between Gadgetbridge and Bangle.js

Sync alarms from the scheduler library on the bangle so they show up in the device alarms for the bangle device in Gadgetbridge. And vice versa?

How should creating and deleting alarms via Gadgetbridge and on the bangle impact each other? When connected and when disconnected?

~~BUG: Currently adding an alarm via gadgetbridge and selecting all 7 days of the week sets an alarm on the bangle, but only to be run once - not all days.~~ fixed with https://github.com/espruino/BangleApps/pull/3178

This issue is duplicated [on BangleApps repo on github](https://github.com/espruino/BangleApps/issues/2795) and [on Gadgetbridge repo on codeberg](https://codeberg.org/Freeyourgadget/Gadgetbridge/issues/3152).

Also reference https://github.com/espruino/BangleApps/pull/2782 introducing setting alarms and timers via the Bangle.js App Loader. Given that pull request I don't think this issue is time sensitive, punintended.

I think this would be a a nice quality of life improvement though. After I have gotten some feedback on this I'll probably try to tweak this.
