837 feature request add latex option for intermediate results

[GerjanDorgelo]

Description

• Adds latex option for intermediate results, for example when
  • so that comparison formula not only shows OK/NOT OK, but also an UC.
  • used for complex equations.
• Updated two equations (that i need anyway) to show how this feature would work.
• Also noticed that two equations lacked a return symbol, which broke the small refactor i made. These two have now a return symbol.

Fixes #837

Type of change

Please delete options that are not relevant.

• New feature (non-breaking change which adds functionality)

• I have added tests that prove my fix is effective or that my feature works
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• New and existing unit tests pass locally with my changes

Pull Request Overview

This PR implements a new feature to display intermediate calculation results in LaTeX formula representations, addressing issue #837. The change allows formulas to show not just the final OK/NOT OK result, but also intermediate computational steps like unity check values.

Key Changes:

• Added intermediate_result field to LatexFormula class for displaying intermediate calculation steps
• Updated formula rendering logic to include intermediate results in complete representations
• Implemented unity check calculations in formulas 6.5 and 6.9 to demonstrate the feature
