add domian search to orgs query

BE PR dependency

After PR

You can now:

auth.org().fetch_orgs_by_query(
    FetchOrgsByQueryParams {
        domain: Some("example.com".to_string()),
        page_size: Some(10),
        page_number: Some(0),
        order_by: Some(FetchOrgOrderBy::CreatedAtAsc),
        name: None,
        legacy_org_id: None,
    }
)

This will only return orgs that have an exact match to the search term w/ either its primary domain or one of its additional domains.
