Don't recommend insulin when `minPredBG` < 54 mg/dL

* New function `minPredBGFromReason` to pull `minPredBG` from the `reason` of an OrefDetermination
* Add header in red above Treatment button when `currentBG` or `minPredBG` are < 54 and a non-external bolus is entered
  * Revert coloring Treatment button red when these conditions are met
* Add bolus amount to confirmation dialog
* l18n automations
