feat: add marketing video mode and Remotion marketing video project

Add debug-only Marketing Video Mode toggle that enables hands-free
screen recording across the app: auto-scrolling Featured Trips carousel,
auto-filling trip wizard, smooth trip detail scrolling via CADisplayLink,
and trip options auto-sort with scroll.

Add Remotion marketing video project with 6 scene compositions using
image sequences extracted from screen recordings, varied phone entrance
animations, and deduped frames for smooth playback.
