Added new BumperEndpoints to the API for managing bumper templates and variants, enhancing the channel management capabilities. Removed outdated bumper-related commands and handlers from the application, streamlining the codebase and improving maintainability. Updated ChannelEndpoints to reflect these changes and ensure proper routing for the new endpoints.
Enhanced the README.md file by adding new SonarCloud badges for coverage, bugs, code smells, security rating, and maintainability rating. Updated the CI workflow to remove coverage collection from the test step, as it is now handled by SonarCloud, streamlining the process and ensuring accurate badge representation.
