refactor: use navigateToSessions helper in session-filters spec

[empiricalrun]

Summary

Replaced inline session navigation code in tests/session-filters.spec.ts with the existing navigateToSessions() helper from tests/pages/sessions.ts.

What changed

The test was manually duplicating these 4 lines:

await page.goto('/');
await expect(page.getByText("Lorem Ipsum", { exact: true }).first()).toBeVisible();
await page.getByRole('link', { name: 'Sessions', exact: true }).click();
await expect(page).toHaveURL(/sessions$/);

These are already abstracted in navigateToSessions() (used by sessions.spec.ts, session-file-upload.spec.ts, and tool-execution/session.spec.ts). This file just missed the import.

Result

• Added import of navigateToSessions from ./pages/sessions
• Replaced the 4 inline lines (+ comments) with a single await navigateToSessions(page) call
• Test passes ✅: https://reports-r2.empirical.run/test-gen-chat-agent/1775019142591/index.html
