Add support for dynamically changing settings with an activated workflow engine (v2)

[Andrew-S-Rosen]

This PR is a collaboration with @honghuikim. It is a continuation of #2163 that addresses changes introduced in #2276. For additional history on this PR, please refer to #2163.

The focus of this PR is to enable dynamic changing of Pydantic model settings when using an active workflow engine. This is achieved, in large part, through a new settings_swap keyword argument to the decorator.

Closes #2147.
