Use scaling factors in solve_strongly_connected_components

[dallan-keylogic]

Dependent on #3993.

Fixes #3785.

Summary/Motivation:

Projects like PrOMMiS are increasingly relying on IDAES's BlockTriangularizationInitializer, which in turn relies on solve_strongly_connected_components. However, in models that need significant amounts of scaling, the initialization raises an error that the constraint residuals are not small. That's because BlockTriangularizationInitializer takes constraint scaling into account but solve_strongly_connected_components does not.

This PR finishes addressing that problem by adding a function to copy scaling factors from one block to another and adding an option to solve_strongly_connected_components to allow

Changes proposed in this PR:

• Adds copy_scaling_factors_to_block function.
• Adds option to use this function to copy scaling factors to temporary blocks in solve_strongly_connected_components

AI-Use Disclosure

Notes for reviewers (optional): My use of unittest.mock in the testing here was deliberate and not a result of using AI. It allows us to test which options are being passed to subfunctions, the number of times those subfunctions are called, and avoids needing to call IPOPT or another full solver.
