feat(alpr): render camera markers on Navara

Separate native scene ownership from shared ALPR source and selection state,
and add bounded Navara sprites with the existing direction/card overlay.
Preserve marker artwork, picking, floor retries and source attribution.

Fix lost post-render wakeups and redundant mobile rail mutations, and keep
HUD typewriter dimensions stable so static views settle without extra frames.
Add parser-fed dev/preview and legacy evidence, including retained failures.
Common W2 terrain and combined performance gates remain open.
