Allow cursor-based pagination to query extra page until collection is empty

[nogates]

What does this PR do?

Mirrors datadog-api-client-java#3790 and datadog-api-client-go#3769 for the TypeScript client.

Cursor-based paginators now keep querying until the response collection is empty (results.length === 0), instead of stopping early when a page returns fewer items than the requested limit (results.length < pageSize). This prevents missed items when a page happens to return fewer results than the limit without being the last page. Page-offset and page-number paginations keep their existing behavior.

• 24 cursor-based WithPagination methods updated across 13 v2 API files (Audit, CI Visibility Pipelines/Tests, Container Images, Containers, Events, Logs, Metrics, Processes, RUM, Security Monitoring, Spans, Test Optimization).
• 21 offset/page-number-based methods remain unchanged.
• Added trailing empty-response cassettes for ListSecurityFindings and SearchSecurityFindings pagination tests.

Additional Notes

The supporting cassettes (extra trailing {"data":[]} response) for most cursor-based endpoints were already added previously. Only the two Security Findings cassettes needed new empty-response entries.

Review checklist

Please check relevant items below:

• This PR includes all newly recorded cassettes for any modified tests.

• This PR does not rely on API client schema changes.

  • The CI should be fully passing.

• Or, this PR relies on API schema changes and this is a Draft PR to include tests for that new functionality.

  • Note: CI shouldn't be run on this Draft PR, as its expected to fail without the corresponding schema changes.
