FEAT: Fresnel extension

[Samuelopez-ansys]

Description

This pull request introduces a new Fresnel extension for HFSS, enabling extraction of Fresnel coefficients from Floquet port simulations for periodic structures. It adds documentation, integration into the extension catalog, and comprehensive system tests for the new functionality. Additionally, several improvements and bug fixes have been made across the codebase, including enhancements to excitation handling, logging, UI theming, and design exploration.

Fresnel Extension Integration

• Added new Fresnel extension documentation (doc/source/User_guide/pyaedt_extensions_doc/hfss/fresnel.rst) detailing workflows, features, validation checks, requirements, and command-line usage.
• Integrated Fresnel extension into the HFSS extension catalog

Testing for Fresnel Extension

• Added comprehensive system tests for Fresnel extension UI, validation, and coefficient extraction, including edge cases and error handling (tests/system/extensions/test_fresnel.py).
• Integrated Fresnel test project fixture and extended HFSS tests to cover Fresnel port and coefficient extraction scenarios (tests/system/general/test_hfss.py).

HFSS Excitation Handling Improvements

• Improved filtering of excitation names to correctly handle modes and ensure proper mapping to boundary objects (src/ansys/aedt/core/application/analysis.py).

Logging and UI Enhancements

• Fixed desktop logging behavior to disable logs in non-graphical mode and enabled logs by default in extensions
• Improved UI theming by applying custom colors and fonts to SpinBox widgets

Design Exploration Bug Fix

• Corrected setup name mapping in design exploration to use the correct identifier

Hi @maxcapodi78 @SMoraisAnsys, could you please review this new extension?

[SMoraisAnsys]

I can't test the behavior as I don't have the AEDT version but I left some comments.
Would it be possible to improve a bit the extension UI layout ? :)
