fix: Remove RpcEntryNotFound from ClioError (#2661)

Since rippled has its own error codes, all occurrences have been
replaced except for [PR2549](https://github.com/XRPLF/clio/pull/2549),
and the entry has also been removed entirely from Clio’s error enum.
This modification follows the feedback provided in this comment:
https://github.com/XRPLF/clio/pull/2549#discussion_r2394840688

Pending compatible libxrpl — temporarily on hold
