Restructure the agent and tray binary blocks around an auto-detected current-release upload plus a separate legacy/rollback upload that stages a version without seizing current. Order staged versions by version number for the active-version dropdown, add a PE version detect route, and drop stale dev-status tags and manual-staging copy.
Add per-version staging, retention (keep 3), and upload/rollback routes for shopdbagent.exe and the tray exe. Keep upload under endpoints.agentpackage and declare a distinct endpoints.agentupdate permission for the future live-push pipe so app-deploy rights never imply SYSTEM agent replacement.
