Merge bitcoin-core/gui#687: Load PSBTs using istreambuf_iterator rather than istream_iterator

bb5ea1d9a9 qt: Load PSBTs using istreambuf_iterator rather than istream_iterator (Andrew Chow)

Pull request description:

  `istream_iterator` eats whitespace charactesr which causes parsing failures for PSBTs that contain the bytes corresponding to those characters. `istreambuf_iterator` is the correct thing to use here.

  This is a regression in 24.0. https://github.com/bitcoin/bitcoin/pull/25001 accidentally changed the original `istreambuf_iterator` to `istream_iterator`.
