refactor: use navigateToSessions helper in session-filters spec

[empiricalrun]

Summary

Replaced a manually duplicated 4-line navigation block in tests/session-filters.spec.ts with the existing navigateToSessions helper from tests/pages/sessions.ts.

Before

// Navigate to homepage
await page.goto('/');

// Wait for successful login
await expect(page.getByText("Lorem Ipsum", { exact: true }).first()).toBeVisible();

// Navigate to Sessions page
await page.getByRole('link', { name: 'Sessions', exact: true }).click();

// Wait for sessions page to load
await expect(page).toHaveURL(/sessions$/);

After

import { navigateToSessions } from "./pages/sessions";

await navigateToSessions(page);

The logic is identical to the navigateToSessions helper that already existed in pages/sessions.ts — this change simply removes the duplication and uses the shared abstraction.
