project file: export dialog with OTIO/OVE/FCPXML format choice

文件 → 导出工程文件… now opens an in-app dialog (format dropdown:
OpenTimelineIO / Oak / FCPXML + output path) instead of the bare
platform save prompt; OK routes the chosen extension through the
engine's export_project_path. Adds project.export.format i18n across
the 8 packs.
