cleanup: whats new page assets and unused codes

[sapayth]

Summary

This PR removes unused assets and code tied to the What’s New admin page. Dedicated What’s New CSS/LESS files are deleted, their registration and enqueue are removed from Assets and Admin, and the Grunt build no longer compiles those styles. The main admin stylesheet is trimmed so it no longer includes the removed What’s New rules. Built/minified assets and the .pot template are updated to match. Admin behavior is unchanged; only unused styles and references are removed to simplify the codebase and reduce asset size.

Testing Guideline
Check if all page are rendering with proper styling and without any broken CSS in the admin dashboard

Poem

🐰 What's new is gone, the feature's past,
No notices here will ever last,
The CSS cleared, the LESS removed,
Our stylesheets sleek and smoothly grooved!
Hop along, the cleanup's done,
What's old is new when features run! ✨
