+fix(app-shell): block ActionParamDialog submit while a file/image param is uploading; map spec `autonumber` (ADR-0059 follow-ups)
+
+Two follow-ups to the shared-field-widget param rendering (ADR-0059):
+
+- **Upload-in-progress guard.** A `file`/`image` param's value only becomes its
+  fileId once the presigned upload settles, so confirming mid-upload sent an
+  empty/stale value. `FileField`/`ImageField` now surface their upload state via
+  an optional `onUploadingChange` prop (shared `useUploadingSignal` hook,
+  ignored by other widgets); `ActionParamDialog` wires it for `file`/`image`
+  params and disables Confirm (label → "Uploading…", new `actionDialog.uploading`
+  i18n key across all locales) plus blocks submit while any upload is in flight.
+- **`autonumber` spelling.** `mapFieldTypeToFormType` now maps the spec
+  `FieldType` spelling `autonumber` (in addition to the widget-map key
+  `auto_number`) to the AutoNumber widget, so a spec-typed `autonumber`
+  field/param no longer falls through to the plain text input — fixes the object
+  form path as well as action params.

+
+- **Upload-in-progress guard.** A `file`/`image` param's value only becomes its
+  fileId once the presigned upload settles, so submitting mid-upload would
+  send an empty/stale value. The upload widgets now surface their in-progress
+  state via an optional `onUploadingChange` prop (shared
+  `useUploadingSignal` hook, ignored by non-upload widgets); the dialog wires
+  it for `file`/`image` params only and disables Confirm (label → "Uploading…")
+  and blocks submit while any upload is in flight.
+- **`autonumber` spelling.** `@objectstack/spec` spells the type `autonumber`
+  while the widget-map key is `auto_number`; `mapFieldTypeToFormType` now folds
+  both so a spec-typed `autonumber` field/param resolves to the AutoNumber
+  widget instead of the text fallback (fixes the form path too, not just params).
