fix(assistant): enforce id requirement when updating assistant (#10321)

* fix(assistant): enforce id requirement when updating assistant

Ensure assistant id is always provided when updating assistant properties by making it a required field in the update payload. This prevents potential bugs where updates might be applied to wrong assistants.

* refactor(useAssistant): simplify updateAssistant callback by removing redundant id

Update InputbarTools to use simplified callback signature
