fix(cls): load css-tablas-apu.css async to prevent render blocking

Browse Source 
- Add complete APU table column widths to critical-bootstrap.css
- Load css-tablas-apu.css with media="print" + onload for async loading
- Critical styles (column widths, row backgrounds) now inline in <head>
- Full CSS loads non-blocking after initial render

Fixes PageSpeed "Render-blocking CSS" warning (120ms savings)
