fix(simulation): resolve Bevy baseline test panics (#885)

Three root causes: SnapshotBuffer hard-dependency in economy.rs
(Option-wrapped), TickPhase::configure missing from SimulationPlugin
(added idempotent call), and stale golden file after D-192 dropped
the version field (regenerated).

All 6 previously-failing tests now pass with zero regressions.
