feat: Add CA cert fallback when caCertFile fails in download requests
- Fallback to BSL cert when caCertFile cannot be opened
- Combine certificate handling blocks to reuse CA pool initialization
- Add comprehensive unit tests for fallback behavior
This improves robustness by allowing downloads to proceed with BSL CA cert
when the provided CA cert file is unavailable or unreadable.
