* M14: translation catalogs, same system as PhotoCraft
Move the interface translations to PhotoCraft's i18n system: one TSV
catalog per language (crates/ui-egui/src/i18n/ja.tsv), the tl! macro,
entries keyed by command id, context or plural forms, and catalog tests
(format, duplicates, placeholders, command ids).
The 49 existing Japanese strings move over unchanged, plus "Auto". The
language preference now defaults to "auto" and follows the system
language (English when it has no catalog); "en" and "ja" still persist
and unknown values are rejected.
Update docs/localization.md, ROADMAP.md and the misc.prefs-language
parity entry.

* i18n: add Brazilian Portuguese (pt-br) UI translation
Adds Language::PtBr (code pt-br, endonym Português (Brasil)) with serde rename so it persists as "pt-br", registers it in Language::ALL (Preferences ▸ Interface language and ui.set/ui.state) and translates the same 49 menu/command keys as the Japanese table. Extends the i18n tests (table parity, codes, persistence) and updates docs/localization.md.
* M14: strict catalog validation, one-pass fmt, translation assets
Fold in the infrastructure parts of #175:
- `fmt` fills placeholders in one pass, so inserted values (a file name
containing `{n}`) are never substituted again.
- Catalog validation rejects unknown escapes, unknown `@` contexts,
placeholder, ellipsis and plural-form mismatches and duplicates. The
bundled catalogs must have no errors (tests); at run time a bad line is
still only skipped and logged, so the rest of the catalog loads.
- `.tsv` files count as assets in `cargo xtask assets`, with a
`translation` kind that may never come from Adobe; ja.tsv gets its
ATTRIBUTION.toml entry.
- Control-channel test: switching the language keeps documents, their
dirty state and command ids.
Also make the drawing language thread-local, as in PhotoCraft, so
parallel kittest harnesses can't change each other's language.

* M14: Brazilian Portuguese as a TSV catalog
Move #165's Portuguese table into crates/ui-egui/src/i18n/pt-br.tsv
(same 49 strings, plus Auto) and register it in LANGUAGES with
PhotoCraft's Portuguese plural rule (0 and 1 singular). Any Portuguese
locale (pt_BR, pt_PT, pt) follows the Brazilian catalog, as in
PhotoCraft. The catalog is an attributed asset (ATTRIBUTION.toml), and
the docs and parity notes list the new code.
