fix: disable autocomplete on input fields during replay

[heathdutton]

During replay, input fields in the replayer iframe can trigger the viewer's browser autocomplete dropdown, making users think their private data is being leaked.

This adds autocomplete="off" to input and textarea elements when rebuilding the DOM for replay.

Fixes #1587
