feat: ability to add team member as a signer

[anikdhabal]

Feature Description

• I think it would be nice if we provide the ability to choose team members as signers. Display a dialog to select team members as signers in the 'Add Signer' section.

Or

• Autofill the signer input with team members details during. Now it depends on the user whom to keep and whom to remove.

This feature provides additional functionality on top of the current behavior and is only for team signing.

Going to close this for now as this idea should be merged in with this other issue once we're ready for it in the future:

#924

To clarify, we'll probably end up with an autocomplete system where saved contacts and team members pop up.
