style: padronizar dialogs e aplicar formatação Biome

DialogContent: padding p-6→p-10, max-w-lg→max-w-xl.
DialogFooter/AlertDialogFooter: botões com flex-1 (largura igual).
Remove gap-3/w-full redundantes de 12+ dialogs.

Reformatação Biome: line wrapping, import ordering.
Error component renomeado para evitar shadowing do global Error.
