Carousel block view display fails config validation on Drupal 11.4 / Blazy 3.x (obsolete breakpoints)

Problem/Motivation

On Drupal 11.4 with drupal/blazy 3.0.17 / drupal/slick 3.0.7, installing the Varbase profile with the Varbase Carousels extra component fatals during drush site:install varbase:

In ArrayElement.php line 100: The configuration property content.field_media_carousel_slide.settings.breakpoints.xs doesn't exist.

Root cause: the shipped config config/install/core.entity_view_display.block_content.varbase_carousel_block.default.yml carries a legacy Blazy 2.x settings.breakpoints mapping (xs/sm/md/lg/xl). Blazy 3.x removed breakpoints from its config schema, so the profile's extra-components config-action validation rejects the display and aborts the install. This blocks Varbase 9.2.x (Drupal ~11.4) installs.

Steps to reproduce

Install Varbase 9.2.x with the Carousels extra component on Drupal 11.4 (drupal/blazy 3.0.17, drupal/slick 3.0.7): drush site:install varbase fatals with the ArrayElement config-validation error above.

Proposed resolution

Drop the obsolete breakpoints mapping from config/install/core.entity_view_display.block_content.varbase_carousel_block.default.yml (the field_media_carousel_slide.settings.breakpoints block). All other settings, including sizes and current_view_mode, remain valid on Slick 3.0.7 and are kept.
