fix: the provisioning line reads as a key reference, the safe-area test follows margin-inline

lint:i18n-keys took the spread in front of t() for a member call and did not
see native.provisioning.sub; the sentence is its own constant now. The
shell chrome test asks for the logical margins and their right-to-left swap.
