fix(i18n): add values-id resource dir so Indonesian devices pick the locale

Friend's device (system language Bahasa Indonesia) fell back to
English even though values-in exists. Modern Android devices report
the Indonesian locale as "id" (ISO-639-1 current code; "in" is the
legacy alias) and resource matching is strict. Added values-id as a
copy of values-in in core/presentation and feature/cw (both language
directories ship the same translations).

Verified: check_strings OK (9 files incl. values-id);
:app:compileDebugKotlin BUILD SUCCESSFUL. Not released (batch with
pending fixes).
