fix(p2pk): show P2PK balance

[mariocynicys]

This makes it so we don't auto-convert P2PK addresses to P2PKH addresses, thus we can query them for balances if they have any.

Also refactors utxo::output_script() to auto detect the address type without the need for a keys::Type flag.

Fixes #720

Missing unit tests for the balance addition. Verified it's working as expected with manual tests though.

@mariocynicys can you please fix failing docker tests compilation by running this command cargo test --test 'docker_tests_main' --features run-docker-tests and checking the errors. You can wait for https://github.com/KomodoPlatform/komodo-defi-framework/pull/1960 to be merged first but don't forget to check these errors after that.

@mariocynicys As discussed, we should also implement P2PK outputs spending in this PR. You should wait for the merge of the conflicting PR first for this too.

[mariocynicys]

The changes made up till now (showing p2pk balance) are reviewable. p2pk spending isn't added yet.

update: removed the under review status so the CI doesn't complain, still reviewable though.

@mariocynicys please fix conflicts in this PR so that we can review it.

@shamardy, sorry, missed the last suggestions. Done now.

There seems to be some of this pattern in this test file though. Let me try to handle these as well in this PR.

@smk762 if you have time, can you please check if your comment here https://github.com/KomodoPlatform/komodo-defi-framework/issues/720#issuecomment-1527182643 is resolved? If I merged it before that, you can check this in dev :)
