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

The Hungarian catalog lacked a row for 1,853 of the status and error
messages that the untranslated report finds in the sources, so the
status bar showed those messages in English.

- hu.tsv gains 1,813 `@msg` rows: the errors of commands and their
  parameter checks, scripts, file import and export, printing and
  plug-ins. The translations are VectorCraft's own, written from the
  English meaning with the catalog's conventions and its existing
  feature names. Placeholders, parameter names, command ids and
  literal values stay as the English writes them.
- The 38 rows that open #7211, #7116 and #7330 add to hu.tsv are left
  out, since a second row for the same key fails
  bundled_catalogs_are_consistent. The report lists those 38 and two
  messages that no catalog has a row for. Menu strings, `tl!`
  literals, undo labels and swatch names are unchanged.
- Two of the messages have two placeholders in a row. The catalog does
  not load such a row, so those two are still shown in English. The
  row for `{k} has control characters{_1}` does not match the File
  Info error for a multi-line field, where the last placeholder is
  empty.
- The Hungarian row of docs/localization-parity.md gives the catalog's
  current message counts.

   - The status bar translates the limits a plug-in run can exceed (its instruction, time and memory budgets and its output size) and the error of a plug-in removal that leaves the plug-in's grant in the plug-in store, in every language that translates every message. The untranslated-strings report also lists messages that an error or a status takes from a `&str` constant (`plugin_limit_errors_are_translated`, `message_scan_reads_messages_held_in_constants`).
   - The status bar translates the plug-in host's other errors (manifest, module and run checks, the output an importer, exporter or effect returns, and the approval a plug-in's permissions need) in every language that translates every message. A JSON object or array inside a message stays as written, and a message that wraps another one, such as `plug-in manifest: {0}`, is matched by its own row before a row that starts with a placeholder. The reasons inside these errors (what is wrong with a parameter's spec or dialog keys, the value a parameter needs, what is wrong with an object, stroke, paint or effect in a plug-in's output) are translated with them, and the untranslated-strings report lists the reasons the plug-in host's error helpers take (`plugin_messages_are_translated_in_every_complete_catalog`, `plugin_errors_translate_with_their_values`, `plugin_error_reasons_are_translated_with_the_error`, `message_scan_reads_plugin_helpers`, `templates_that_start_with_text_match_first`).
   - The status bar translates the errors a script's `File` and `Folder` objects, `vc.run`, `$.evalFile`, the `$` object's properties and functions, `alert`, `confirm` and `prompt`, `vc.document` and `vc.log` raise, the limits a run can pass, and the errors of Drop Script Engine, and the line for a run that fails (a syntax error, a thrown error, a limit, a stop or an internal error, with the script's name, the line and column, the included file it is in and the files left written), in every language that translates every message. The script's name, paths, numbers, command ids and the text a script throws itself are shown as they are. A failure with no line and column, such as an error in code `eval` compiled, is shown with one colon after the script's name (`an_error_without_a_place_names_the_script_and_kind`). A message template that names a value twice matches only when both places hold the same text, so the line for a failed run is not taken for the message inside it (`a_repeated_placeholder_matches_the_same_text`). The untranslated-strings report also lists the messages the script host's `fail`, `value` and `over` helpers take and the errors the script interpreter throws, and a constant's text comes from the file or crate that declares it, so the Scripts menu's headers are not listed as messages (`script_errors_are_translated`, `script_host_errors_are_translated`, `message_scan_reads_script_interpreter_errors`, `message_scan_reads_constants_of_the_file_and_its_crate`, `message_scan_skips_test_modules_with_any_test_cfg`).
+  - The Hungarian catalog (`crates/ui-egui/src/i18n/hu.tsv`) has an `@msg` row for the status and error messages the untranslated report (`untranslated_report`) finds in the sources, 3,444 `@msg` rows in all: the errors of commands, scripts, file import and export and plug-ins. The report lists 40 Hungarian messages: the composite font, justification order and connect end errors that open #7211, #7116 and #7330 translate, and two messages that no catalog has a row for. The status bar does not use the rows for ``unknown parameter `{within}{key}`; {why}`` and `{name} must be {lo}–{hi}{unit} (got {v})`, because a message with two placeholders in a row cannot be matched (`Template::parse` in `crates/ui-egui/src/i18n/catalog.rs`). The row for `{k} has control characters{_1}` does not match the File Info error for a multi-line field, where the last placeholder is empty. A native speaker has not reviewed the wording.
   - Localised UI: menus (in-window and native), panels, dialogs, toolbar and Preferences read from per-language catalogs (`crates/ui-egui/src/i18n`, see `docs/development.md`); Traditional Chinese (Taiwan), Simplified Chinese (mainland), Japanese, Korean, Vietnamese, German, Spanish, French, Italian, Polish, Brazilian Portuguese, Russian, Ukrainian, Georgian and Catalan ship complete, and Czech covers every menu label (and more), with system-locale detection on macOS, Windows, Linux and the web (the browser's languages, or `?lang=`), a Language preference and, on macOS, a VectorCraft ▸ Language menu. Names are never translated (fonts and their styles, layers, artboards, saved presets, user libraries, custom workspaces, recent files, plug-ins).
     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`).
