What Problem This Solves

Two legacy Android Compose surfaces remained after their only entry points were removed:

• SettingsSheet was orphaned when PostOnboardingTabs was deleted in 17777b3a9ff.
• ChatSheetContent was orphaned when its ChatSheet wrapper was deleted in cd86107a10f.

The dead files retained about 1,600 lines of unreachable UI, stale source-inventory entries, and several unused Android helpers and design-token accessors.

Why This Change Was Made

• Delete the two unreferenced legacy Composables.
• Move the two still-live initial-chat helpers into ChatScreen.
• Rename their tests to match the surviving owners.
• Remove exact-zero-reference Android properties and token accessors.
• Regenerate the native i18n source inventory.
• Correct stale Android source-of-truth paths in apps/android/style.md.

Current ShellScreen continues to own the active ChatScreen path, and SettingsScreens remains the active settings implementation.

User Impact

No intended behavior change. This removes unreachable Android code and stale generated inventory while preserving the active chat and settings surfaces.
