feat: Add solitaire game implementation

[Vertixx01]

Description

I made the solitaire game work and have it in a stable version that I tested — everything was working fine.

Motivation and Context

I just wanted to contribute to random open source projects for practice. This gave me a good chance to learn, practice, and get involved.

How has this been tested?

• Tested manually by playing the game.
• Confirmed everything works as expected.
• Verified that it doesn’t affect other parts of the application.

Screenshots (if appropriate):

Please don't rewrite the opening UI completely when implementing a new game.
I can't merge this if you keep that in your pull request.

The columns get misaligned when there is a card with more than two characters.

Once you fix these two things, we can talk about the rest of it. Thanks!

@Vertixx01 do you mind fixing this?
