fix: Display categories and tags on blog edit form

The edit() action used var-scoped variables passed as extra renderView
named args, which is non-standard in Wheels. Views access data through
the controller's variables scope, but var-scoped variables are local to
the function. Refactored edit() to match the create() pattern: removed
var from blog, categories, postTypes so they are set in controller scope,
and use renderView(template="create") without extra args. Also added
val() to arrayFind comparison to prevent type mismatch between query
iteration types when marking selected categories.
