Description

Redesign MoreOptions entity config screen

• Replace the type-column dropdown table with per-ITIL-type tabs and a
  segmented control (Inherit/No/Yes) for each setting
• Centralize the screen definition (tabs, sections, rows) in Config.php
  instead of the Twig template, so a new or type-specific setting can be
  added in one place
• Extract the segmented control into its own reusable Twig component
• Move plugin CSS into public/css/moreoptions.scss
• Fix inner tabs losing their active state when navigating away from and
  back to the entity tab (GLPI's outer tab script strips .tab-pane
  classes recursively)
