Confirm the studio working context

Confirms the owner's optional studio-wide working context: one bounded paragraph of standing context that spans Projects. Owner-only: guests and non-owner members receive not-found. A confirmed Project working brief takes precedence over it, and the person's explicit request takes precedence over both. It records studio-level standing context as the owner states or corrects it. Each confirmation replaces the whole context. Requires the current revision from account_context_get as expected_revision (0 when none exists); a stale revision fails without overwriting. Retrying the exact same confirmation with the same idempotency_key replays as a no-op, even after a later confirmation; the same key with different text fails closed. An empty context clears it. Confirming never touches sibling account settings, never changes any Project's working brief or direction, and causes no Program edit, Clip, Render, media, publication, or public-link effect.
