Return the RTMP publishing address from register_rtmp_input

[Gawor270]

Description

The composition API now reports a complete RTMP publish URL where it previously reported only a port.

• Regenerated the composition client: RegisterInputResponse.port is replaced by publish_url, and register-input handles the 503 it can now answer with
• register_rtmp_input returns the publish URL instead of None, raising InternalServerError when the server omits it
• Covered the new return value and the missing-address case in tests

Motivation and Context

The publish address can no longer be derived from the composition origin and a port, so the server supplies the whole URL.

Documentation impact

• Documentation update required

Types of changes

• Breaking change (fix or feature that would cause existing functionality to not work as expected)

🟢 Approval recommended

The changes are consistent across client, generated types, and tests, and the updated behavior is explicitly covered by new test cases.

Changes:
