i18n: Simplified Chinese has a row for 1,813 of the messages the untranslated report lists

Adds 1,813 @msg rows to zh-hans.tsv, one for each status and error message the
untranslated report listed for Simplified Chinese, except the 38 that open
pull requests translate in their own rows: the composite font, justification
order and Blob Brush connect end errors. The catalog test rejects a second row
for the same key, so leaving them out keeps the catalog consistent when those
pull requests merge.

The report now lists 40 zh-hans messages: those 38, and two that no catalog
has a row for yet. Its menu, tl!, undo label and swatch name sections are
unchanged. Placeholders, backticked names, quoted values and JavaScript
identifiers stay as in the source.

     The counts that Package's status and question, the folder search of Missing Fonts and Find Linked Files, the modified and missing linked file prompts and the CSS Properties panel's notes show use the interface language's plural forms instead of a fixed "(s)" form. Evidence: `the_missing_links_note_uses_each_count_form` in `crates/ui-egui/src/dialogs/tests_package.rs`, `the_modified_links_question_uses_each_count_form` in `crates/ui-egui/src/dialogs/missing_links.rs`, `search_counts_use_each_count_form` in `crates/ui-egui/src/dialogs/missing_fonts/tests.rs` and `the_unnamed_objects_note_uses_each_count_form` in `crates/ui-egui/src/panels/tests_css_properties.rs`.
     The status bar's messages for relinked, replaced, updated and embedded images, broken links, linked files that can't be read or changed on disk, images that can't be decoded, added and unavailable fonts, copied CSS, downloads and exports with their notes name one item in the singular and more in the plural, in English and in each language's plural forms (`counted_status_messages_take_the_plural_form` in `crates/ui-egui/src/i18n/tests.rs`).
     The status bar's messages for documents opened or saved with notes and for discarded or restored recovered documents, and the Global Edit options' Results line, do the same (`open_save_and_recovery_messages_take_the_plural_form` in `crates/ui-egui/src/i18n/tests.rs`); the warnings for linked images and placed documents output as their previews and the errors for a page past a placed file's last page or artboard name their counts in the singular or the plural in English.
+  - The Simplified Chinese catalog (`crates/ui-egui/src/i18n/zh-hans.tsv`) has an `@msg` row for the status and error messages the untranslated report (`untranslated_report`) finds in the sources, 3,439 `@msg` rows in all: the errors of commands, scripts, file import and export and plug-ins. The report lists 40 Simplified Chinese messages: the composite font, justification order and Blob Brush connect end errors that open #7211, #7116 and #7330 translate, and two messages that no catalog has a row for yet. A message with two placeholders in a row (`Template::parse` in `crates/ui-egui/src/i18n/catalog.rs`) is still shown in English.
   - Edit › Undo and Edit › Redo, in the in-window and native menus, name the step in the interface language as the History panel lists it (`panels::history::step_name`), so when the catalog has no plain row for a step named after an effect, such as Feather, the menu shows the translation of the effect's menu row without its ellipsis (`undo_and_redo_name_the_step_as_the_history_panel_does`).
   - The History panel translates the undo step names the engine, the tools and the shell write as literals: the untranslated report (`untranslated_report`) lists any a complete catalog lacks, and a step whose catalog row exists only with an ellipsis (such as an effect's menu name) shows that row without the ellipsis.
   - The History panel menu has Step Backward and Step Forward, which run Edit › Undo and Edit › Redo and are disabled when there is no step to undo or redo, and Set History Limit…, which opens Preferences at Performance, where History States is set.
