Switch to a Default Varbase Bootstrap Paragraphs recipe and drop the use of the Module Installer Factory class for permissions

Problem/Motivation

Varbase Bootstrap Paragraphs grants role permissions via Vardot\Installer\ModuleInstallerFactory::addPermissions() (scanning config/permissions), which silently skips a missing role instead of validating. Following the Drupal core Recipe approach already used on Varbase API, Varbase Media and Varbase Blog makes this declarative and validated.

Steps to reproduce

Proposed resolution

Move the role permission grants into recipes/default/recipe.yml (config actions only, module installation stays as-is), drop config/permissions/, and call the recipe at the end of varbase_bootstrap_paragraphs_install() instead of addPermissions().
