test: add HTTPS test cases for CORS wildcard subdomain matching
This adds comprehensive test coverage for HTTPS subdomain wildcard matching
in TestMatchesOrigin:
- https exact match
- https no match
- https wildcard subdomain match
- https wildcard subdomain no match (base domain)
- https wildcard subdomain no match (different domain)
- protocol mismatch tests (http pattern vs https origin and vice versa)
The matchWildcard function was already working correctly - this just adds
test coverage for the HTTPS cases that were previously untested.
Note: The cache invalidation is already handled synchronously by
setBucketMetadata() which is called via:
- UpdateBucketCORS -> UpdateBucketMetadata -> setBucketMetadata
- ClearBucketCORS -> UpdateBucketMetadata -> setBucketMetadata
Added clarifying comments to document this call chain.
