/// A reactive filter input derived from `HyleFiltersState`.
///
/// Looks up the field definition in `state.fields`, reads the current value
/// from `state.form_data`, and calls `state.set_field` on change.
///
/// By default it renders:
/// - `Boolean` fields → `<select>` with "Any / Yes / No"
/// - `Reference` fields → `<select>` populated from pre-resolved `options`
/// - Everything else → `<input type="text">` (or the `input.kind` hint from
///   the blueprint, e.g. `"search"`, `"number"`)
///
/// Pass `render` to replace the default for a specific field:
///
/// ```rust,ignore
/// FilterField {
///     state: filters,
///     field_key: "role",
///     render: |props| rsx! { MySelectInput { props } },
/// }
/// ```
///
/// # Props
/// - `state` — the `HyleFiltersState` from `use_filters`
/// - `field_key` — the field name to render
/// - `render` — optional custom renderer receiving `HyleFilterFieldProps`
