Fix faction ammunition resupply and settings recovery

Wait for both convoy cargo phases and use actual magazine stock. Resolve empty primary weapon ammunition from muzzle metadata and recover cleanly from failed initial settings saves.

Update native fixtures, scoped cleanup guards, packaging evidence and validation documentation. Make reviewed fixture tests checkout-relative. All repository checks pass against the isolated staged tree; native resupply completion and multiplayer qualification remain outstanding.
