feat(validation): add custom validation rules for Git repository URLs and branches

- Introduced `ValidGitRepositoryUrl` and `ValidGitBranch` validation rules to ensure safe and valid input for Git repository URLs and branch names.
- Updated relevant Livewire components and API controllers to utilize the new validation rules, enhancing security against command injection and invalid inputs.
- Refactored existing validation logic to improve consistency and maintainability across the application.
