With the MCP plugin enabled, payload.auth() can return a
payload-mcp-api-keys doc instead of a User. Add an isPayloadUser
type guard and use it in every server action, page, and route that
treats the auth result as a real user, so API-key sessions can no
longer pass user auth checks. hasRoles now explicitly requires a
users-collection doc.
- Fetch current user's leadOrActual preference in roster page via payload.auth()
- Add RosterDisplayContext to avoid prop drilling through org chart components
- MemberCard shows 'Lead' or 'Actual' based on user preference
- Add preference radio buttons to PreferencesForm under Display section
- Update updatePreferences server action to save leadOrActual
- Add TODO for restyling radio buttons later
- Resolve parents via subAssignments instead of inferred member overlap
- Drop cyclic or dangling subassignment edges
- Render members only at their deepest unit; widen unit boxes and pluralize member counts
