[feat] handle dash of input name in form builder ui

[vittxr]

Setting an input name with a dash generates an invalid Zod form schema

using dash in names will generates:

const formSchema = z.object({
  map - name: z.string().min(1),
  map - farm: z.string(),
  map - vehicle: z.string(),
  map - files: z.string()
});

I think the name input in the builder UI shouldn't allow dashes or should just replace them with underlines.
