fix: enhance test stability and error handling for worktree operations

- Updated feature lifecycle tests to ensure the correct modal close button is selected, improving test reliability.
- Refactored worktree integration tests for better readability and maintainability by formatting function calls and assertions.
- Introduced error handling improvements in the server routes to suppress unnecessary ENOENT logs for optional files, reducing noise in test outputs.
- Enhanced logging for worktree errors to conditionally suppress expected errors in test environments, improving clarity in error reporting.
