[TNZ-27070]: Fix UAA on standard ports

[joemahady-comm]

Fix UAA on standard ports with mismatching Location and Destination

[Copilot]

Pull Request Overview

This PR fixes UAA SAML authentication issues when dealing with standard ports by implementing URL normalization. The fix ensures that URLs with explicitly specified standard ports (80 for HTTP, 443 for HTTPS) are treated as equivalent to their counterparts without explicit port numbers during destination validation.

Key changes:

• Added URL normalization functionality to handle standard port equivalence
• Updated SAML authentication provider to use normalized URLs for destination validation
• Added comprehensive test coverage for the new normalization functionality
