fix: app route path nesting (deploy/remove/templates), server.js fetchT import, lifetime license expiry, workflows path prefix

- routes/apps/index.js: mount sub-routers at '/' to avoid double-nesting (was /deploy/deploy, now /deploy)
- server.js: add fetchT import for workflow engine init
- license-manager.js: fix isExpired() for lifetime licenses (null expiresAt → always expired)
- src/app.js: add '/workflows' path prefix to prevent requirePremium gating all routes
- app-templates.js: fix 10 templates missing volumes/healthCheck
- routes/apps/index.js: add e.stack to error logging for better debugging
