test: add E2E test to verify no RSC prefetch on team page load

[emrysal]

What does this PR do?

Adds an E2E test to verify that the prefetch={false} fix in PR #27260 is working correctly. The test ensures that no RSC prefetch requests (requests with _rsc query parameter) are made for event type pages when loading the team page, which was causing excessive Google Calendar API rate limit hits.

• Follow-up to fix: disable prefetch on team page event type links to prevent Google rate limits #27260

Updates since last revision

• Changed test from checking prefetch on hover to checking prefetch on page load (per Sean's request)
• Fixed overly broad regex that was catching unrelated RSC requests - now specifically matches only /team/{teamSlug}/{eventTypeSlug} pattern
• Renamed function to countEventTypePrefetchRequests for clarity

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. N/A - test only
• I confirm automated tests are in place that prove my fix is effective or that my feature works.

How should this be tested?

Run the E2E test locally:

PLAYWRIGHT_HEADLESS=1 yarn e2e team-page-no-prefetch.e2e.ts

The test:

1. Creates a team with event types
2. Navigates to the team page (/team/{slug})
3. Waits for page to fully load (networkidle + 3 second buffer)
4. Intercepts RSC prefetch requests matching /team/{teamSlug}/{eventTypeSlug} pattern
5. Asserts that zero event type prefetch requests are made on page load

Expected result: Both tests pass, confirming that prefetch={false} prevents Next.js from prefetching event type pages when they enter the viewport.

Human Review Checklist

• To validate the test catches real issues, temporarily remove prefetch={false} from team-view.tsx and verify the test fails
• Consider if the 3 second timeout is sufficient to catch prefetch requests in production builds
• Verify the regex ^/team/${teamSlug}/[^/]+$ correctly matches event type URLs without false positives

Checklist

• My code follows the style guidelines of this project
• I have commented my code, particularly in hard-to-understand areas
• I have checked if my changes generate no new warnings
