Merge bitcoin/bitcoin#30395: rpc: Use untranslated error strings in loadtxoutset

fa5b8920be rpc: Use untranslated error strings in loadtxoutset (MarcoFalke)
fa45865778 refactor: Use named arguments to get path arg in loadtxoutset (MarcoFalke)

Pull request description:

  Motivation:
  * Some are not translated at all, anyway. See https://github.com/bitcoin/bitcoin/pull/30267#discussion_r1663631973
  * For others translation is not yet needed, because they are not called by the GUI (yet)
  * For others translations will never be needed, because they are RPC code. See https://github.com/bitcoin/bitcoin/pull/30267#discussion_r1663611194

  Also, while touching this:
  * Remove the trailing `\n`. See https://github.com/bitcoin/bitcoin/pull/30267#discussion_r1663647981
  * Add back the path. See https://github.com/bitcoin/bitcoin/pull/30267#discussion_r1663666751
  * Use named args to get the path.
