feat(git-gate): source-IP-keyed multi-tenant repo namespace (PRD 0070)
First slice of git-gate consolidation: make the smart-HTTP git backend
serve every bottle from one process, selecting each request's repo root by
the calling bottle's source IP — the same attribution invariant + resolver
the multi-tenant egress addon uses. `git daemon` can't source-IP-route per
connection, so the consolidated gateway serves git-gate over this HTTP
backend (the transport firecracker/macOS already use); wiring the docker
path onto it lands with the launch-integration slice.

- policy_resolver: factor out `_post_resolve`; add `resolve_bottle_id`
  (source IP -> bottle id, same fail-closed 403->None contract as
  `resolve`) — the git-gate has no policy blob to parse, the bottle *is*
  the namespace.
- git_http_backend: `resolve_repo_root(resolver, base, source_ip, token)`
  — single-tenant passthrough when no resolver; else `<base>/<bottle_id>`,
  fail-closed on unattributed / resolver error / namespace escape.
  `BOT_BOTTLE_ORCHESTRATOR_URL` (same env as egress) flips the shared
  gateway multi-tenant; the identity header is read for attribution and
  never forwarded to the CGI. Per-repo creds + hooks scope by repo dir, so
  isolating the root per bottle isolates its creds too.

Single-tenant path unchanged (existing real-git-push tests green). New unit
coverage for the resolver + repo-root selection matrix. Full unit suite
green (1690 tests; the 13 test_sidecar_init /bin/sleep errors are the
pre-existing NixOS-local noise).
