11b7269d83a56f919f9dddb7f7c72a96d428627f script: Enhance validations in utxo_snapshot.sh (pablomartin4btc) Pull request description: This PR resolves #27841 and some more: - Ensure that the snapshot height is higher than the pruned block height when the node is pruned (Suggested by @Sjors [here](https://github.com/bitcoin/bitcoin/pull/28553#issuecomment-1804941396)). - Validate the correctness of the file path and check if the file already exists (@hazeycode's [#27845](https://github.com/bitcoin/bitcoin/pull/27845)). - Make network activity disablement optional for the user (Suggested by @Sjors [here](https://github.com/bitcoin/bitcoin/pull/16899#discussion_r342735815) and [here](https://github.com/bitcoin/bitcoin/pull/16899#issuecomment-536520911)). - Ensure the `reconsiderblock` command is triggered on exit (@hazeycode's same PR as above), even in the case of user interruption (Ctrl-C). In order to perform some testing please follow the instructions in the description of previous @hazeycode's PR #27845.
