Showing moment of signing on Quotation

The wish is that after the client signs the quote, the quote itself is updated and the date/time of signing is also displayed on the official quote.

Optionally, one would like the client to fill in a text box on the quotation itself, and that they sign the quotation with this and that this makes the quotation officially signed and that this is displayed here immediately.

Afterwards, the updated quote is sent to the client and updated in the Building Portal environment.
