Add tap-to-edit oneliner on case detail screen

Tap opens the Wear OS system input picker (voice/keyboard/handwriting),
pinned to de-DE for medical German vocabulary. Doctor-authored oneliners
latch a manual flag that blocks the simulated LLM burst from overwriting
them; a subsequent manual edit still wins.
