Guard media insert with handleInsert and add debug logs

Prevent errors when inserting images into the editor by checking that the
handleInsert callback exists before calling it. The editor was failing to
insert images because handleInsert could be undefined; adding conditional
guards around double-click and insert-button code paths avoids runtime
exceptions. Also add temporary console.log statements to help debug what
assets and handleInsert look like during interactions.
