Adds the 22 strings introduced by the provider-selection series (#4971,
#4973, #4975, #4976) to all 33 locales with real translations, plus the
per-locale CLDR plural forms for the quota batch-failure message and the
hand-curated en _one/_other variants.
Keys were appended without running the scanner's removeUnusedKeys pass,
which would have pruned unrelated live translations; the diff is
additions only. Terminology matches each locale's existing sync strings
(library, reading progress, highlights, storage quota).
