refs #8126, #8221, #8223 ✨ New 'Proxy' for all helper requires - this is not currently enforced, but could be, much like apps - the proxy object is HUGE - changed date to use SafeString, this should have been there anyway - use the proxy for all helpers, including those in apps 😁 ✨ 🎨 Single instance of hbs for theme + for errors - we now have theme/engine instead of requiring express-hbs everywhere - only error-handler still also requires express-hbs, this is so that we can render errors without extra crud - TODO: remove the asset helper after #8126 IF it is not needed, or else remove the TODO 🎨 Cleanup visibility utils 🎨 Clean up the proxy a little bit 🚨 Unskip test as it now works! 🎨 Minor amends as per comments
