Make settings searchable by original English labels in localized UI

When the Codex UI is localized, Settings search should match both the localized label and the original/canonical English label.

For example, documentation and support discussions may refer to a setting as Thread detail, while the Japanese UI displays it as 出力の詳細度. Searching Settings for Thread detail in the Japanese UI currently makes the setting difficult or impossible to discover.

Requested behavior

Index both of these for each setting:

• the localized display string
• the canonical/original English string

Optionally, related aliases could also be indexed where useful.

The displayed result can remain fully localized; this request is only about search/discovery.

Why this matters

Developers frequently use localized UI while documentation, GitHub issues, release notes, AI assistants, and discussions refer to UI controls by their English names. Translation can also be non-literal, so guessing the localized term is unreliable.

Supporting canonical English aliases would make it much easier to follow English documentation without switching the entire application language.

This is similar in spirit to #21373, which requests canonical English aliases for slash-command search in localized UI, but this request specifically applies to the Settings search/index.

No file or test is named; start by locating the Settings search/index implementation and the setting metadata that provides localized labels. Verify how search results are tested, then ensure each setting is discoverable by both its localized label and canonical English label while the displayed result remains localized.
