Subject: [PATCH] fix(navara): disable redundant sun shadows in minimal look

Minimal inherited the sun light default of castShadow=true although the photoreal tiles carry baked lighting. Use the same no-shadow sun configuration as cinematic. The focused 3-run city gate improved from C4.6/N5.1 ms (1.1087) to C4.6/N4.9 ms (1.0652) with 12000 vessels. Full Node 24 tests and allocation gates, boundaries, format, build and panel build pass.
