feat(i18n): localize ConfigSection and ConfigScope labels (11 MessageIds)

[gordonlu]

Summary

Localize the 9 ConfigSection labels (Provider, Model, Permissions, Network, Display, Composer, Sidebar, History, MCP) and 2 ConfigScope labels (SESSION, SAVED) in the config view.

Changes

• localization.rs: Add 11 new ConfigSection* and ConfigScope* MessageId variants with translations across all 7 shipped locales (En, Ja, ZhHans, ZhHant, PtBr, Es419, Vi)
• views/mod.rs: Update ConfigSection::label() and ConfigScope::label() to accept Locale and delegate to tr(). Update all call sites to pass locale.

Testing

• Existing tests updated to use Locale::En explicitly where they assert section/scope labels
• 4338/4339 tests pass (pre-existing macOS flake: legacy_sse_closed_stream_reconnects_and_retries_tool_call)
• cargo fmt --all -- --check passes

Code Review

This pull request localizes the configuration section and scope labels in the TUI views by adding corresponding message IDs and translations across multiple languages (English, Vietnamese, Chinese, Japanese, Portuguese, and Spanish). It updates ConfigScope and ConfigSection to retrieve localized labels using the current locale, and adapts the configuration view rendering and tests accordingly. The review feedback highlights an issue where filtering in non-English locales will no longer match English terms (like 'display' or 'session'). It suggests updating the filter logic to match against both the localized and English labels to preserve search usability.

When using a non-English locale, filtering the configuration view using English terms (such as "display" or "session") will no longer match because the section and scope labels are fully localized. Since these are common technical terms, it is highly beneficial to allow filtering by both the localized labels and their English/canonical equivalents.

We can achieve this elegantly by formatting the search strings to include both the localized and English labels.

        let section = format!("{} {}", row.section.label(self.locale), row.section.label(Locale::En)).to_lowercase();
        let key = row.key.to_lowercase();
        let value = self.row_display_value(row).to_lowercase();
        let scope = format!("{} {}", row.scope.label(self.locale), row.scope.label(Locale::En)).to_lowercase();

Thanks @gordonlu — we merged #2891 and #2896 from your i18n batch tonight, which moved localization.rs on main, so this slice now shows as conflicting. Could you rebase it onto current main when you get a chance?

Since the slices all touch localization.rs, the smoothest path is to rebase and push them one at a time, oldest-first (#2892 → #2901 → #2918 → #2919 → #2921 → #2926 → #2929 → #2932 → #2940) — we'll merge each promptly so the next rebase stays small. Sorry for the churn; the batch is exactly the right shape and we want all of it.
