fix: include branch information in scan parameters for repository scans

- Store branch name in context when provided via --branch flag
- Include branch in scan_parameters dict sent to backend API
- Fixes issue where branch_name and branch_id were null in JSON export

This ensures that when scanning a specific branch with 'cycode scan repository --branch <branch>',
the branch information is properly sent to the backend API so it can populate branch_name and
branch_id fields in the detection details.
