Move public axum response tests off direct HandlerRegistry construction so the checked test surface follows interactions()/on() just like canonical examples.

Add InteractionForm::parse for common typed field extraction and use it in example interaction handlers to avoid repeated string parsing plumbing.

Wrap extracted interaction forms in an InteractionRequest with a concise dispatch path, add a handlers() helper, and move canonical examples off direct HandlerRegistry/InteractionForm plumbing.

Add a SafeHtml PageRequest path for shell/partial composition and migrate examples so rendered hemplate fragments stay typed through the transport boundary instead of round-tripping through unchecked strings.

Add InteractionForm::for_handle so tests and public integration code can construct dispatched forms from generated Handle<T> values instead of raw numeric handle ids.
req: ceremony/004
req: public_api/001
Add HandlerRegistry::register_handle for generated Handle<T> values and migrate examples away from passing raw numeric handle ids at registration sites.

Cover the integration boundary for CSRF-style hidden fields: InteractionForm keeps arbitrary form fields available to app/auth extractors instead of dropping them during dispatch parsing.
