Fixed the cabinets not opening interactive session issue

[coderranger2]

Closes #105

Bug found

Clicking Play on arcade cabinets only updated coins/xp and showed a placeholder state. No interactive game session opened for the selected cabinet.

Root cause

1. playCard() only handled rewards and score updates.
2. No active game state was being stored, so the UI never rendered a playable session component.

Fix applied

1. Added activeGame state and updated cabinet click handlers to pass the full card object instead of only reward values.
2. Updated playCard() to:

• set active game
• start game session
• switch to mini games view

3. Added conditional rendering for interactive gameplay screen using selected cabinet data.

Testing done

1. Reproduced the bug before applying fix
2. Confirmed fix resolves the issue
3. Verified existing features are not broken
4. Tested on Chrome 147/1920 x 1080 desktop
