Add bitmap font rendering toggle feature

[taovuokko]

I consistently encounter issues where text in Firefox and Thunderbird appears thin, ragged, and hard to read, especially with fonts like Calibri. The issue persists even after installing the required fonts. After some research, I found that the solution is to disable bitmap font display.

This pull request adds a simple toggle for bitmap font rendering, which can significantly improve text appearance.

What I added:

• New script: 3-toggle-bitmap-font-rendering.sh in commands/system-setup/
• Updated list.rs to include the new option under "System Setup"

How it works: The script creates or removes a fontconfig file that disables embedded bitmaps for all fonts. Users can easily toggle this feature on/off through the CLI menu, with clear instructions provided.

This small change can make a big difference in readability without manual config edits.

I think I like it ! But I havent checked the code 😸

Very interesting, I never knew this was a thing I'll test this out.

Issue primarily affects older Microsoft Office fonts. The rendering engine typically uses embedded bitmap images in fonts, designed for Windows rendering. However, this approach doesn't work well with most Linux rendering engines. This configuration disables bitmap usage, forcing vector rendering instead.

I've personally had to face this problem numerous times, as my day job requires use of Calibri font. Even slight size reductions make it blurry and hard to read on Linux systems

Sorry for the inconvenience. We had a massive restructure of the codebase to improve future development. Because of this can you update your PR to the new structure. Thank you for your assistance and contribution.
