i18n: French translates every status and error message the report lists

fr is in COMPLETE_MESSAGES, but the untranslated report listed 1,842
status and error messages with no French row, so with the interface in
French those messages showed in English.

- fr.tsv gains 1,842 `@msg` rows in one block after the last row. The
  translations are VectorCraft's own, written from the English meaning
  with the catalog's terms and typography (no-break space before
  : ; ? ! and inside « »). Placeholders, backticked names, command ids,
  double-quoted values and bare true, false and null stay as the
  English writes them.
- The untranslated report now lists no French messages. Menu strings,
  `tl!` literals, undo labels and swatch names are unchanged.
- The French row of docs/localization-parity.md gives the catalog's
  current counts.
