fix(ui): _configureDetailButtons trapped in unterminated JSDoc

Stray /** at shared.js:604 wrapped the function body in a block comment
that only closed at line 747, so _configureDetailButtons was never
defined. renderOrderDetailModal threw ReferenceError, leaving the order
detail modal stuck on "Se incarca...".

Removed the orphan /** opener; bumped shared.js cache-bust to v=49.
