Add dark theme and console listing improvements

[AcTePuKc]

What changed

• Added persisted light/dark themes to the Explorer and Bruteforcer interfaces.
• Added the sun/moon theme toggle and corrected dark menu, dialog, input, grid, and progress styling.
• Improved Bruteforcer layout behavior, progress completion/reset, disabled-control readability, and themed progress cells.
• Added optional console listing flags: --sort-size, --human-size, and --no-timestamp.

Why

These changes address the dark-theme and console-listing usability issues while keeping the default console output behavior unchanged.
