Add E2E tests for user roles and scope filtering

[erseco]

Added a Playwright E2E test file (tests/e2e/specs/documentate-roles-scope.spec.js) to verify the Documentate_Scope_Filter functionality logic and WordPress role capabilities mappings work well together.

The test ensures:

• Administrator: Can see and interact with all documents in the CPT list view.
• Editor: Can only see documents within their assigned documentate_scope_term_id and subcategories.
• Author: Can only see their own created documents, within their assigned documentate_scope_term_id (this confirms author capabilities correctly mesh with scope filter).
• Subscriber: Encounters a WP-die restricted access message when attempting to navigate to the documents list, properly enforcing capability barriers.

The script runs automated data setup for categories, users with specific scopes and posts using wp-env integration. All tests run locally via Playwright logic mimicking admin UI usage.

Use a fresh browser context before role-specific login

Using context.newPage() here reuses the test context's existing auth state, and this suite is configured to preload storage-states/admin.json in tests/e2e/playwright.config.js, so the page is already logged in as admin before the editor/author/subscriber login flow starts. In that state, visiting /wp-login.php does not provide the normal login form, so filling #user_login/#user_pass can fail (or keep the admin session), which makes the role-based scope assertions unreliable. Create an isolated browser context (or explicitly clear/logout auth) before attempting each non-admin login.
