CLAUDE: Fix /reset-image AttributeError by updating owner_only function

The owner_only() function was accessing ctx.author.id, which caused an
AttributeError when called with Interaction objects from slash commands
(which use .user instead of .author).

Updated both utils.py and helpers/utils.py to handle both Context and
Interaction objects by checking for .user first, then falling back to
.author for backward compatibility with traditional commands.

Fixes: Command 'reset-image' raised an exception: AttributeError:
'Interaction' object has no attribute 'author'
