* Use URL type in most outstanding struct fields
This fixes all known remaining cases where url fields are stored as
plain strings, with the exception of form fields where empty strings
are used as sentinels (see `diesel_option_overwrite_to_url`).
Tested for regressions in the federated docker setup attempting to
exercise all changed fields, including through apub federation.
