/**
 * Unit Tests for TeamPanel Component Logic
 *
 * Tests the business logic for team management panel including:
 * - Seat configuration display by tier
 * - Invite button visibility based on role and seats
 * - Upgrade prompts for lower tier users
 * - Seat limit warnings
 *
 * This prevents regressions where:
 * - Users on tier1/tier2 couldn't see upgrade prompts
 * - Invite button wasn't shown for eligible users
 * - Seat limits weren't properly enforced
