Fix Android config save feedback and mirror watch reading layout

Gray out Save until settings are dirty, add a Cancel button that
discards edits, reorder ReadingScreen to match the watch's
build_content() (adds the missing Attitude/Outcome preview and the
day-significance rank/count), and fix UI chrome to follow the app's
own language setting instead of system locale (values-de/strings.xml
+ appStringResource()/localizedContext()).
