Remove legacy code

Add the list of known dependencies as an .md file

These changes were originally made to simplify the interface of how data was added to the model and facilitate easier testing. This led to some overrides being ignored however breaking the ability to add workspaces in multi input mode for the FQ and convolution tabs. As this PR is just supposed to be removing uneeded code. I have reverted these changes for now and removed the tests they enabled.

re: #28418

Previously m_continuous was not being set in this case and was just being left to a default. In most cases this was defaulting correctly to true but was causing issues with Ubuntu on the build servers.
