[ENHANCEMENT]: Initialize My Progress with default difficulty_id: 1 for all games

[master-of-none]

What feature are you enhancing?

The initial My Progress database entry created for a new user

What improvement would you like to see?

Set up the default my_progress JSON to include all existing games with a difficulty_id value of 1. This structure should be automatically inserted during user creation (e.g., post-Google sign-in or standard registration). Example structure:

{
  "progress": [
    {
      "game_id": 1,
      "difficulty_id": 3
    },
    {
      "game_id": 2,
      "difficulty_id": 1
    },
    {
      "game_id": 3,
      "difficulty_id": 1
    },
 ]
}

How will this benefit users?

• Ensures every new user has a consistent starting point in all games
• Prevents UI crashes due to missing keys in progress tracking
• Simplifies frontend logic by avoiding null checks for my_progress
• Supports personalized difficulty scaling in future updates
