fix(#613): remove 77 unused string resources (#616)

Independently verified dead weight: computed defined vs used set across
all source sets (R.string.* in Kotlin + @string/* in XML/manifest).
Zero references in app/src/main, androidTest, or test fixtures.

- values/strings.xml: -77 unused <string> entries (818 -> 741)
- values-ko/strings.xml: -67 corresponding entries (704 -> 637)

Build: ./gradlew assembleDebug BUILD SUCCESSFUL (no missing-resource errors).

True KO translation gap after prune = 741 used EN - 637 translated KO = 104
(previously mis-stated as 114; the 67 removed were never translated anyway).
