refactor(gateway): remove the single-tenant data-plane paths (audit #400 finding 3)

All three backends (docker, firecracker, macos-container) now launch through
the consolidated orchestrator, and every production gateway sets
BOT_BOTTLE_ORCHESTRATOR_URL — so the legacy single-tenant (`resolver is None`)
branches in the shared gateway's data plane were unreachable dead code, a second
security-relevant path to keep correct in parallel with the live one. Make the
orchestrator resolver mandatory and delete the single-tenant paths from the
three data-plane modules.

egress_addon.py: drop the static routes file entirely — EGRESS_ROUTES, _reload,
the SIGHUP handler, self.config, and the SUPERVISE_BOTTLE_SLUG env slug. The
per-request /resolve is the only policy source; __init__ fail-closes if
BOT_BOTTLE_ORCHESTRATOR_URL is unset. Introspection (`_egress.local/allowlist`)
now reports the calling bottle's *resolved* routes. The block/redact log gates
and _req_ctx redaction now read the per-flow config/env from the request-time
stash, so they use each bottle's log level and token set (they silently used the
empty static config before). Nothing sends `docker kill --signal HUP` to the
gateway in the consolidated model (the egress applicators fail closed), so
removing the SIGHUP reload is safe.

git_http_backend.py: resolver mandatory; no flat-root fallback. main() refuses
to start without an orchestrator URL; a request whose source resolves to no
bottle 404s.

supervise_server.py: resolver mandatory; every proposal is attributed to the
source-IP-resolved bottle. Remove handle_list_egress_routes (the proxy-fetch
introspection that only worked when the proxy carried one bottle's identity) —
list-egress-routes is answered from the resolved policy. main() refuses to start
without an orchestrator URL.

Tests: a host-side fake resolver serves each test's Config through the real
parse path (a small YAML-subset emitter round-trips route_to_yaml_dict); the
response/websocket hooks stash it as request() would. Deletes the tests for the
removed static-config, SIGHUP-reload, and single-tenant-passthrough paths; adds
fail-closed-without-orchestrator coverage.

Follow-up: gateway_init still forwards SIGHUP to the egress child (now dormant —
no one sends it); the README still describes the docker backend's per-bottle
topology. Both are outside the data-plane teardown.
