/**
 * E2E test: Notion Integration Flows.
 *
 * Covers:
 *   8.1.1  Notion OAuth Flow — OAuth login button appears in setup wizard
 *   8.1.2  Scope/Permissions Selection — backend called with correct skillId
 *   8.1.3  Workspace Validation — app handles workspace info after OAuth
 *   8.2.1  Read-Only Access Enforcement — Notion skill listed in Intelligence page
 *   8.2.2  Write Access Enforcement — write tools accessible when connected
 *   8.2.3  Initiate Page/Database Creation — create actions available
 *   8.4.1  Manual Disconnect — Disconnect flow with confirmation dialog
 *   8.4.2  Token Revocation Handling — app handles revoked token gracefully
 *   8.4.3  Re-Authorization Flow — setup wizard accessible after disconnect
 *   8.4.4  Permission Upgrade/Downgrade Handling — re-auth with changed scopes
 *   8.4.5  Post-Disconnect Access Blocking — skill not accessible after disconnect
 *
 * The mock server runs on http://127.0.0.1:18473 and the .app bundle must
 * have been built with VITE_BACKEND_URL pointing there.
