DOC-1907: Add Paginate Messages stub (#556)

* DOC-1907: Add Paginate Messages and Pipeline Events stub

Single-sources the Paginate Messages and Pipeline Events page from the
docs repo (redpanda-data/docs#TBD). Adds a stub under Consume Data, a
nav entry, and a What's New March 2026 entry for the Redpanda Console
unlimited-pagination feature.

* [TEMP] Point docs source to DOC-1907 branch for preview

Must be reverted before merge. Allows the deploy preview to resolve the
include directive against the companion docs PR branch.

* DOC-1907: Narrow stub + What's New entry to messages only

Pipeline-events pagination is covered in a separate PR. Update the stub
title/description, the What's New March 2026 entry, and switch the nav
label to empty brackets so it auto-resolves from the page title.
