fix: align combustion thresholds across engine (upstream 080c286c, adapted)

One direct / retrograde orb table (Moon included) in the shared
COMBUSTION_ORBS / is_combust, used by the full reading and the consultation
graha-drishti layer. TASK-upstream-sync5-20261002 U3.

(cherry picked from commit 080c286c, resolved onto our shared helper)
