fix(i18n): keep legacy "in" locale config for old Indonesian devices

Root cause: aapt2 merges values-in into values-id (in is the legacy
alias of id), so the APK only carried the (id) config. New devices
report "id" and match; older devices report "in" and find no (in)
config -> fall back to English (friend's report: only system date
showed Indonesian).

Fixes:
- Add values-in-rID (core/presentation + feature/cw) so the APK
  keeps a real "in" language config; values-in and values-id both
  get translatable="false" on the 27 entries that English marks
  (aapt2 rejects those with multiple %-substitutions otherwise)
- Verified: aapt2 compile of values/values-in/values-id/values-in-rID
  OK; :core:presentation:mergeDebugResources + :feature:cw:mergeDebugResources
  BUILD SUCCESSFUL
