/// A generic field that shows an Insert button to create a related entity inline.
///
/// Usage:
/// - Provide `fieldKey` for where to store the selected/created value
/// - Provide `label` for display
/// - Provide `relationTitle` for the modal header
/// - Either provide `fieldSchema` (preferred, like OneToOne/OneToMany) or `formFieldsBuilder`
/// - Provide `onCreate` callback which receives form data and returns created entity map
/// - Configure `valueKey` to pick what to write back (e.g., 'id') into the parent controller
/// - Optionally set `displayKey` to show a summary of the selected value
