Is your feature or enhancement related to a problem? Please describe.

Currently, the signature input has no option to insert a prepared HTML snippet.
We have a streamlined HTML signature in our company that is perfectly formatted for all devices. Would be great if we can also use it in Chatwoot.

Describe the solution you'd like

Enable HTML input in the signature editor and disable stripping html entities.
