- Make the mission split sidebar drag-resizable (220–560px, persisted) so
long mission titles aren't trapped behind a fixed-width column.
- Move card tags (autopilot/health/status) to a row below the title and
drop the overflowing "Active: …" line.
- Collapse mission creation to a single AI-driven entry point: rename
Sparkles to "Create New Mission" and remove the manual "+" button.
