fix(orchestrator): supersede a prior active bottle at the same source IP

register() used INSERT OR REPLACE keyed on bottle_id, so re-registering an
existing source_ip with a new bottle_id left TWO active rows for that IP.
by_source_ip fail-closes on ambiguity (>1 active -> None), so the reused IP
was then bricked to a 403 on egress resolve — even for hosts its own policy
allowed. Happy path (fresh IPs, teardown on stop) never hit it, but IP reuse,
crash recovery, or a persisted registry DB across an orchestrator restart
(now that ensure_running always recreates the container) all could.

register() now deletes any other active row at the same source_ip before
insert; the fail-closed ambiguity guard stays as defense in depth. Adds a
unit test for the supersede, and a docker integration test
(test_multitenant_isolation) that drives two bottles through one shared
gateway and asserts each gets only its own injected token and its own
allowlist — the core PRD 0070 multi-tenancy invariant, previously only
verified by hand.

 ## Architecture
 
-On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a gateway attached to both that internal network and a NAT egress network. The agent gets HTTP(S)_PROXY and CA bundle env vars pointing at the gateway's internal-network IP, so HTTP/HTTPS traffic flows through the gateway instead of direct egress. `bottle.git` / git-gate is intentionally deferred on this backend until a safe Apple Container key-delivery path exists.

The VM reaches the gateway over a per-bottle point-to-point TAP link; a dedicated fail-closed `nftables` table (`inet bot_bottle_fc`) confines the guest to that link, so nothing leaves the box except through the gateway. The TAP pool and nft table are provisioned once (root); per-launch needs no privilege.

-"""Consolidated bottle launch sequence for the Firecracker backend (PRD 0070).
-
-Mirrors bot_bottle.backend.docker.consolidated_launch but wired for
-Firecracker's TAP-based network topology instead of a shared Docker bridge.
-
-The per-bottle sidecar bundle (one `docker run` per bottle, published on the
-slot's host-side TAP IP) is replaced by a single persistent gateway that
-every Firecracker VM shares. The gateway runs as a Docker container in the
-dev-harness (a Firecracker VM is stage B per PRD 0070), with its ports
-published on the host (`0.0.0.0:PORT`). VMs reach it at their slot's
-host-side TAP IP because Docker's iptables PREROUTING DNAT redirects
-port 9099/9100/9420 traffic to the gateway container — a path the nft
-isolation table already allows via `ct status dnat accept` in the forward
-chain.
-
-Attribution is by the VM's guest IP, which is unspoofable by construction:
-the /31 point-to-point TAP topology + the `bot_bottle_fc` nft table ensure
-that only the expected VM can source-IP that address.
-
-Sequence:
-  1. ensure the Firecracker-flavoured orchestrator + gateway are up;
-  2. register the bottle by its guest IP (attribution key) → bottle id +
-     identity token;
-  3. provision its git-gate repos/creds into the running gateway;
-  4. fetch the shared gateway CA for the provisioner to install in the rootfs.
-
-The TAP slot allocation, rootfs build, and VM boot are the caller's job.
