feat(nextjs): Migrate sendDefaultPii to dataCollection

[chargome]

Migrate sendDefaultPii usage in the Next.js package to the dataCollection API:

• withServerActionInstrumentation: Use getDataCollectionOptions().httpBodies.includes('outgoingResponse') to gate server action response recording
• addHeadersAsAttributes: Use httpHeaders.request from getDataCollectionOptions() to control header span attributes and filtering level
• setUrlProcessingMetadata: Remove the sendDefaultPii gate — URLs are fundamental request metadata, not PII-gated data (see spec update)
• pagesRouterRoutingInstrumentation: Remove the sendDefaultPii gate for route params — same reasoning as URLs

Feat PR lacks integration or E2E test coverage

Low Severity

This is a feat PR that migrates multiple code paths from sendDefaultPii to the dataCollection API, but the diff only includes unit tests (with heavy mocking). No integration or E2E test is present to validate the end-to-end behavior of these data-collection changes within an actual Next.js application. Per the review rules, feat PRs need at least one integration or E2E test. Flagging this because it was mentioned in the rules file.
