The timeline_count_label, timeline_loading, timeline_filtered_count, and timeline_zoom_in keys were never referenced from src/. Felix's review flagged them as 15 dead strings to translate. Removed across de/en/es; the timeline_dragging_aria_live key is kept and will be wired up in the next commit. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
