Fix iOS sync by converting field types to int (#5081)

Browse Source 
It seems the iOS clients are not able to handle the `type` key within the `fields` array when they are of the type string.
All other clients seem to handle this just fine though.

This PR fixes this by validating it is a number, if this is not the case, try to convert the string to a number, or return the default of `1`.
`1` is used as this is the type `hidden` and should prevent accidental data disclosure.

Fixes #5069

Possibly Fixes #5016
Possibly Fixes #5002
