Merge fixes for #95 + #71 on current main

- Project panel Clear (#95's focus routing) goes through invoke, so deleting
  items that compositions use still asks first (M3.16).
- ui_project_delete: let a dialog finish egui::Modal's sizing frame before
  clicking its buttons (#95 moved dialogs to egui::Modal).
- #71's i18n / theme tests clear the frame's texture delta; egui asserts on
  unhandled deltas in debug builds.
