Summary

Fix incorrect URL construction when route-based multi-tenancy is enabled and the client uses an absolute endpoint base URL.

Changes

• Preserve the scheme, host, and port when inserting tenant segments into absolute URLs.
• Correctly position the tenant before the authentication base path.
• Validate and encode tenant route segments.
• Preserve existing behavior for disabled tenancy and non-route transports.
• Add regression tests covering relative and absolute URLs, transport modes, and invalid tenant values.

No breaking API changes.
