feat(templated_uri): add try_effective_port method

[martintmk]

Adds a fallible variant of effective_port on Origin and BaseUri that returns a UriError when the authority does not specify a port and the scheme has no well-known default known to this crate (http, https).

(noticed that this could be useful when using the effective_port in our codebase)

Pull request overview

This PR adds a fallible “effective port” accessor to templated_uri so callers can get a Result<u16, UriError> instead of Option<u16> when the scheme has no default port known to the crate.

Changes:

• Added Origin::try_effective_port() returning an error when the port can’t be inferred.
• Added BaseUri::try_effective_port() delegating to Origin.
• Added tests and doc examples for the new APIs.

Please address both Copilot comment - remove crate:: from UriError and add negative test case
