1.0.40: fix icon sizing (adaptive XML) + semantic status colors

- Restore mipmap-anydpi-v26 adaptive icon XMLs so Android 8+ shows
  the icon at full size instead of scaling it to 66% safe zone
- Foreground at 108dp sizes (108-432px), background #050E05
- Status colors now semantic (not tied to app red/orange theme):
  SUCCESS=green, SYNCING=blue, FAILED=red, PARTIAL=orange, CONFLICT=amber
