Returns every translatable text key of an owned page for one configured target locale: the source text the runtime translates from, the current target text, and the targetGeneration a writeback must replay.

• Sources are resolved server-side from the item value, its component-schema default, or the project default language overlay (whichever the runtime actually translates from). Client-supplied schemas or bare item ids are never trusted.
• translation: null means no row exists, or the stored one answers a source the merchant has since changed. "" is a deliberate clear.
• targetGeneration is the raw stored target value at read time (null = no row, "" = cleared). Replay it verbatim on POST.
• language.isDefault is true when the locale is the project default language; POST refuses to write it.
• Not cached: a cached generation would guarantee a stale write.
• Text only. Image translations are not exposed here; use GET /projects/{projectId}/translation-units?kind=image.

Workflow: GET this page and locale, change translation on the entries you want to write, POST them back unchanged otherwise, then GET again to confirm.
