bark: add is_cpfp to WalletTxInfo
Carlos needs this to improve bark-web.
When doing an exit each CPFP appears in the onchain wallet as a separate entry.
This is somewhat confusing to users.
We will provide him the is_cpfp-field in the rest API so he can properly explain/label/hide these transactions in the UI.
I also ensured the response of bark onchain transactions corresponds to the one in the REST-API
- check or remove this line after you've added a CHANGELOG entry or if your PR doesn't need one (they should go into
CHANGELOG/unreleased/)
