9. test: make orphan inherit-rejection getdata checks able to fail

   PeerTxRelayer.assert_never_requested compares the hash of every request
   received, an int, with its argument, and test_orphan_inherit_rejection
   passed it hex strings. An int never equals a str, so these checks passed
   whatever the node requested. Pass ints instead.
   
   Two more changes let the checks see the requests they are about:
   
   - Relay the parent from peer2 rather than peer1. Relaying it made the
     node request it from peer1, so the check that peer1 never requested
     the parent fails once it compares ints.
   - Bump mocktime by TXREQUEST_TIME_SKIP before the peer1 and peer2
     checks. The node requests an orphan's missing parent after a delay,
     so without the bump the request has not been sent when they run.
   
   Also correct the comment on why the parent is rejected: it exceeds the
   maximum standard weight, and the node rejects it with tx-size.
   
   To check each assertion can fail, the scenario was mutated in a scratch
   copy so that the node does request the hash, and each call site was
   evaluated with both the old and the new argument. The old one passed
   every time, and the new one failed:
   - parent not relayed: peer1 is asked for the parent, peer2 for the
     child's txid;
   - child not relayed: peer2 is asked for the child's txid;
   - child relayed from peer2: peer2 is asked for the child's wtxid;
   - neither child nor grandchild relayed: peer3 is asked for the child's
     txid.
   Without the mocktime bumps, the first two mutations pass with ints too.

10. test: require an int in PeerTxRelayer.assert_never_requested

    The requests it checks carry int hashes, so any other type never
    matches and the check passes whatever the node requested.

12. test: look for the wtxid in p2p_blocksonly

    The connection that checks a transaction submitted over RPC is not
    announced to a block-relay-only peer uses P2PTxInvStore, which negotiates
    wtxidrelay. The node would therefore announce the transaction by its
    wtxid, and the assertion looked for the txid, which cannot be in the
    store for a transaction carrying a witness: it passed whether or not the
    transaction was announced.
    
    Assert on the wtxid instead. With the connection opened as
    outbound-full-relay rather than block-relay-only, the old assertion still
    passes and the new one fails.
    
    Also open an outbound-full-relay connection and assert that the wtxid
    was announced on it. The two assertions differ only by `not`, so if the
    announcement or its id changes, the test fails instead of the absence
    check passing silently.

16. gui: wallet: Use v0 PSBT

    PSBTv2 is not very interesting for current GUI users, and defaulting to
    it causes issues for existing users. To make this change minimal and
    avoid touching strings, this commit, only changes the default back
    instead of making the version configurable.
    
    The external signer PSBT will still be version 2, and I've added an
    explicit argument here to show that. This will break users who are using
    HWI versions < 2.1.0.
