Bundles four reference script overlays (cedapug_maps, l4d2center_maps, competitive_rework, tickrate) and adds a `flask seed-script-overlays` CLI that upserts each *.sh as a system-wide overlay. Test deploy invokes it after the orphan-cleanup migration so fresh test servers come up with the same overlays the user has been maintaining by hand.
