Hannah Wolfe 243b387063 Helper Proxy & single express-hbs instance (#8225)
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

// # Plural Helper
// Usage: `{{plural 0 empty='No posts' singular='% post' plural='% posts'}}`
//
// pluralises strings depending on item count
//
// The 1st argument is the numeric variable which the helper operates on
// The 2nd argument is the string that will be output if the variable's value is 0
// The 3rd argument is the string that will be output if the variable's value is 1
// The 4th argument is the string that will be output if the variable's value is 2+
