Remaining non-generated non-reason-parsed files

Summary:
We are rolling out exact-by-default object type syntax to www. In order to do that, we need to turn all implicitly inexact objects `{}` into explicitly inexact objects `{...}`.

This diff has no runtime or type checking changes.

I generated this diff by first finding the non-generated files in www that still had implicit inexact objects. After adding `implicit-inexact-object=error` to the flowconfig, I ran:
```
flow --lazy-mode none --show-all-errors | grep -P "\w[^ ]*:[\d]+:[\d]+" -o | sed 's/:.*:.*//' | sort | xargs grep -L -P '@(partially-)?generated' > ~/files_to_codemod
phps CodemodConfigRunner CodemodConfigExactByDefault -m local -i ~/files_to_codemod
hg st -n | xargs -n 1000 hg commit -m "codemod"
```
