fix(MWPW-190279): locale-aware line-break rules for DE, BR, RO, JP in prompt-bar

[dstrong23]

Summary

Fixes MWPW-190279 — line breaking issues visible in the prompt-based Unity block on localized pages (de-DE, pt-BR, ro-RO, ja-JP).

Although the affected pages have since been migrated to the new upload marquee experience, the underlying block had no locale-aware line-breaking rules. This fix makes the block robust for future use across both hero-marquee and upload-marquee contexts.

Root Cause

The .inp-wrap .inp-field textarea and heading/body text elements in unity-enabled marquee blocks had no overflow-wrap, word-break, or locale-aware line-breaking rules. Languages like German and Romanian produce long compound words that overflow fixed-width containers without these guards. Japanese requires CJK-specific line-breaking rules (word-break: keep-all, line-break: strict) that differ from the Latin-script approach.

Changes

File: unitylibs/core/widgets/prompt-bar/prompt-bar.css

Base rule (all locales):

• Adds overflow-wrap: break-word, word-break: break-word, and hyphens: auto to heading and body text elements inside .hero-marquee.unity-enabled and .upload-marquee.unity-enabled interactive areas
• Adds overflow-wrap: break-word and word-break: break-word to .inp-wrap .inp-field (the prompt textarea)

Japanese override ([lang="ja-JP"]):

• Applies word-break: keep-all and line-break: strict to follow JIS line-breaking rules
• Uses overflow-wrap: anywhere (instead of break-word) to handle edge cases like Latin strings or URLs typed into a JA context
• Clears hyphens: auto (not applicable to CJK)
• Applies to both heading/body text and the .inp-field prompt input

This follows the existing [lang="ja-JP"] locale override pattern already present in this file.

Testing

• Verify heading text wraps correctly on de-DE, pt-BR, ro-RO locales (no overflow)
• Verify Japanese heading text respects JIS line-breaking (no mid-character breaks)
• Verify prompt input field handles long localized strings without overflow
• Verify no visual regression on en-US baseline
