feat: add additional validation checks for DisputeGameFactory upgrade

[VolodymyrBg]

This commit adds additional validation checks for the DisputeGameFactory upgrade process:

Pre-checks:

• Verify that new implementations are valid contracts
• Ensure the DisputeGameFactory owner is correct
• Confirm that new implementations differ from current ones

Post-checks:

• Verify implementations are correctly set
• Check that implementations have valid versions
• Ensure implementations are properly initialized
• Confirm that game types are correctly registered

These additional checks improve the safety and reliability of the upgrade process
by catching potential issues before and after the implementation change.

These checks are not needed beyond what is already there. Thanks though!
