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.
Replace hasRoles calls with hasPermission in all server actions and page
components. Update qualification checks (logistics, intelligence) to use
permission-based checks instead of role name matching. Update staff lookup
in tickets/staff.ts to query roles collection. Use enlistmentDate field
on profile page instead of createdAt.
