Fix HTTP host header in url() function

Changelog category (leave one):

• Bug Fix (user-visible misbehavior in an official stable release)

Changelog entry (a user-readable short description of the changes that goes into CHANGELOG.md):

Fixes HTTP requests made by the url() table function to properly include port numbers in the Host header when accessing non-standard ports. This resolves authentication failures when using presigned URLs with S3-compatible services like MinIO running on custom ports, which is common in development environments. (Fixes #85898)

@scanhex12 Thanks for the approval. Any guidance on whether the failing tests are related to the change? To me they look unrelated but this is also my first PR against the ClickHouse repo.

@tomquist it's okay, failed tests are really unrelated - it's our CI problem. I'll merge your PR
