refactor: define canvas UI as an SDK client tool (#1797)

* refactor: define canvas UI as an SDK client tool

Send a JSON-defined canvas_ui_client tool on new, profile-based, and resumed conversation requests while retaining the legacy Python registration for persisted conversations. Normalize the new SDK event kinds to the existing Canvas UI rendering.

* fix: omit canvas client tool from ACP launches

* refactor: rename canvas client tool

Use the semantic canvas_ui_control name and contain the SDK-generated action discriminator behind exported constants.
