Adds submitterName/submitterEmail state and setters to useFormDraft and
wires them through start/saveDraft/submit. Previously the Contactgegevens
name/email were held in a local page ref and never made it into any
request body, so submissions landed in the DB with NULL submitter fields
and a mid-form reload wiped whatever the user had typed.
- useFormDraft: internal submitterName/submitterEmail refs with setters
that mark the draft dirty (same debounced-PUT path as field values),
sessionStorage resume via draft_submitter:{token}, and a
MISSING_SUBMITTER guard in submitForm so empty fields surface as
submitError without hitting the endpoint.
- register/[public_token].vue: deletes the local submitter refs and
reads/writes through the composable; onSubmit pre-validates and
bounces the user back to the Contactgegevens step with a snackbar
when fields are missing.
- SaveDraftBody / SubmitBody: optional public_submitter_name and
public_submitter_email per the documented backend contract.
