Merge bitcoin/bitcoin#30879: test: re-bucket long-running tests

f5a2000 test: re-bucket long-running tests (willcl-ark)

Pull request description:

  Re-bucket:

  - `p2p_node_network_limited -v*transport`
  - `feature_assume_utxo`

  On CI runners these tests are taking longer than their current bucket suggests, often being among the last to finish.

  Re-bucket them to improve CI efficiency.
