fix(panel): group Intake / Secretary / root PR Reviewer as Support, not Board

The Board is the three oversight roles — Product Owner, Head of Marketing, Auditor. Intake (Prompter), the Secretary, and the root PR Reviewer are CEO-direct helpers (per the org chart), but they carry team=board internally, so both agent groupings bucketed them under 'Board' — and on the agents page the helpers were even duplicated into both Board and On-Demand. They now render in a dedicated Support group in the journals list and the agents page; cell PR reviewers keep their cell's team and stay grouped under that cell. Board is now exactly PO/HoM/Auditor.
