Pull request overview

This pull request adds a per-repository toggle to control whether review approvals should be synchronized to GitLab merge requests. This feature allows administrators to selectively enable/disable approval synchronization for individual repositories, providing more granular control over GitLab integration.

Changes:

• Added a new gitApprovalSync boolean field to the Repository entity with a default value of true to maintain backward compatibility
• Updated the message handler to check the repository's approval sync setting before synchronizing reviewer state changes to GitLab
• Added a checkbox control in the repository admin form under the Integrations section (only visible when GitLab integration is configured)
