QA all Data Review Center flows on production

Manual QA pass on https://dashboard.texturehq.com (production). Requires: (1) Will-identity production dashboard auth, (2) Notion write access for documentation page, (3) screenshot-capable browser harness, (4) Linear write access for filing child bug issues in ALL/Data Review Center QA project. None of these are wired up in will-engineer workspace — this is a human-or-harnessed-QA-session task, not a coding sub-agent task.
