Cardano Updates

Signed-off-by: Chris Gianelloni <[email protected]>

The ouroboros-consensus source-repository-package reference has moved
upstream (now e8fb792f), making the sed for the old tag (8f0e1423) a
no-op. Remove it from both Dockerfile.cardano-node-bp and
Dockerfile.cardano-node. The latest leios-prototype also auto-creates
leios.db, so drop that from init-node0.sh.

Extract sev, ns, host, and thread labels from cardano-node JSON logs
and add static service/type labels. This matches the demo x-ray config
and enables the hard-coded Loki query in the UI to work.

Use HOST_ADDR environment variable so connection logs show the actual
node IP, making it easier to infer traffic direction from log entries.

IBs no longer exist in the current Leios protocol design. Remove IB
tracking from analyse.py metrics and entrypoint-analysis.py assertions.

These files were from the previous Antithesis setup that ran sim-rs and
are no longer used by the new cardano-node-based stacks.

* feat: derive HTTP status from retriable flag in error responses

Map retriable=true → HTTP 500, retriable=false → HTTP 400 instead of
returning HTTP 500 for all errors.

* fix: update behavioral tests to expect HTTP 400 for non-retriable errors

Align test assertions with refactored HTTP status code mapping where
retriable=false errors now return HTTP 400 instead of 500.
