Full-node daemon: P2P + Monero's own restricted RPC (the safe-for-public
subset wallets use as a "remote node") are auth:none like bitcoin/electrumx's
equivalents; unrestricted RPC (full node control) stays gated auth:local.
readonly_root works cleanly since the upstream image is FROM scratch with
ownership fixed at build time — no runtime chown/setuid needed, unlike
bitcoin-knots/core.
Verified locally end-to-end before committing: built the upstream Dockerfile,
confirmed the generated Cuprated.toml against `cuprated --generate-config`/
`--dry-run`, and ran the real image with the manifest's exact ports/volumes —
including discovering that cuprated's own 127.0.0.1-default RPC bind is
unreachable through a published host port and needs to bind 0.0.0.0
internally with ports[].bind:127.0.0.1 doing the actual restriction, the
same pattern bitcoin-knots' RPC port already uses in this repo.
Bumps the unauthenticated_ports_are_all_accounted_for canary (26 -> 28) for
cuprate's two auth:none ports, per that test's own review-before-updating
contract.
