[TCE] Draft Romanian (ro) text extract

[veganstraightedge]

About this draft

Auto-generated starter for a new language's TCE YAML. Imperfect and incomplete — a decent starting point but needs manual intervention to finish.

This file is ro.txt — raw pdftotext output, not a YAML file. It lives in the locales folder for convenience but Rails will not load it as a locale. Use it as a text source when hand-writing ro.yml.

Scope of this PR

This PR only adds the draft file. It does not wire up the language. A full TCE language migration also needs:

• Entries in config/application.rb (path_ltr_locales or path_rtl_locales)
• Entry in ToChangeEverythingController::LTR_TO_CHANGE_ANYTHING_YAMLS (or RTL)
• New .scss stylesheet in app/assets/stylesheets/to_change_everything/
• @import line in app/assets/stylesheets/to_change_everything.scss
• HTML formatting (<p>, <br>, <span class="bold">) around body text
• Translated layouts.to_change_everything section (menu/toc labels)
• Short UI labels (video_cte, pdf_cte_html, take_flight_html, next_text) that the extractor couldn't pick up
• Correct image_alt descriptions (currently copied from English)
