settings_upgrade_status_label lived twice per flavor: once for the
Settings row, once as a raw locale-translated string standing in for
what the upgrade screen otherwise composes from the app name and the
tier qualifier. On gplay the two could drift apart -- 15 of 75
locales showed the wrong word order or an untranslated English
fallback where the composed title used the correct language. The row
now composes through the same brandTitle template gplay's own
upgrade screen title already used, so the two can no longer disagree.
FOSS's value was a support ask ("Sponsor CAPod"), not a composed
brand title, so its wording stays untouched -- the key is renamed to
upgrade_foss_sponsor_label (byte-identical text, all 75 locales) and
both FOSS call sites read that one resource instead.
"FOSS" is the flavor's name, not prose. Locale copies of the FOSS badge
and of the composed "CAPod FOSS" title had drifted - some translated the
word, one Thai entry into an unrelated word entirely - all of it shown as
the app's own brand.
Both base entries are now translatable="false" and every locale copy is
gone; with the flag set, any remaining locale entry would trip a fatal
ExtraTranslation in the release lint. The GPlay "Pro" badge is prose and
stays translated.
