Retire the acl-allowlist Docker suite; the decision is proven in-process

The ACL admission decision is exhaustively unit-tested per npub over real
loaded allow/deny files (src/node/acl.rs test module: allow-match-wins,
allowlist-miss falls through, deny-only, deny-all, allow_all override,
deny-after-allowlist-miss), and the inbound and outbound handshake-
admission paths are covered in-process over the loopback transport
(src/node/tests/acl.rs: inbound msg1 denial, outbound denial, reload).
The Docker suite's only unique coverage was admission over a real UDP
transport, which every other real-transport suite already exercises, and
its operator-facing log assertion.

Drop it from both runners in lockstep (its *_SUITES array, run function,
default-flow call, --only dispatch arm, and the GitHub matrix leg with
its steps) so the parity guard stays green, and record the retirement in
the deliberately-not-run block with a pointer to the standalone runner.
The testing/acl-allowlist/ suite stays on disk and runs by hand.
