feat: responsive grid layout and alphabetical sorting for list flags

[kaifcodec]

• Display user and email module listings (-lu and -le) in a responsive rich Table grid filling terminal size
• Render module items inside panels with inner Table grids for pixel-perfect vertical column alignment
• Sort categories and site modules inside each category 100% alphabetically
• Self-adapt panel height for large categories to eliminate massive vertical gaps and scrolling

@brunolm and @kristoisberg try this list layout once and let me know how it looks and whether you think it can be improved or not, right now, I somehow managed to make it look good and level with each column but as the module counts are different in each category it was hard to structure and level them side by side.
