2047983 - Update fluent strings for Settings pane headers that use message references

Status: VERIFIED FIXED

(Firefox :: Settings UI, enhancement)

Description

[akulyk]

Some Settings pane headers (Languages, AI controls, and Downloads) reference the navbar strings instead of defining their own messages.

Fluent message references (e.g. { message-id }) have no fallback: if the referenced message isn't translated in the active locale, the reference itself is rendered as literal text rather than the source-locale value.

Fix: Give these three headers their own dedicated Fluent strings. Include fluent migration so existing translations of the referenced navbar strings are carried over to the new header strings, avoiding re-translation work across locales.

firefox-beta Uplift Approval Request

• User impact if declined/Reason for urgency: For the languages that still don't have translations for the new settings strings (e.g., Ukrainian) some Settings page headers display message reference ( like { pane-languages-title2 } ) instead of actual strings.
• Code covered by automated testing?: no
• Fix verified in Nightly?: yes
• Needs manual QE testing?: yes
• Steps to reproduce for manual QE testing: Manual testing is tricky as we can't change browser language in Nightly, but when navigating to about:preferences#downloads, about:preferences#languages or about:preferences#ai, the page should display it's actual header string.
• Risk associated with taking this patch: low
• Explanation of risk level: Only changes the strings
• String changes made/needed?: 3 strings where changed and migration was provided
• Is Android affected?: no

This issue does not reproduce on the Russion build, but it does reproduce on the Ukranian build (Nightly v154.0a1 20260616140050).
The following incorrect titles can be observed: {pane-downloads-title2}, {pane-languages-title2}, {pane-ai-controls-title2}.

I can confirm the fix in Nightly v154.0a1 20260618200449.
The correct section titles are displayed: Downloads, Languages, AI controls.

The issue still reproduces in the latest live Beta v153.0b1 (build2) and verification will be performed after v153.0b2 will be released.
