refactor(tests): make --zeus-network-alias take the alias as its value

docs/contributing/tests/integration.md

@@ -258,6 +258,7 @@ Tests can be configured using pytest options:
 - `--clickhouse-version` — ClickHouse version, also used for ClickHouse Keeper (default: `25.12.5`)
 - `--schema-migrator-version` — SigNoz schema migrator version (default: `v0.144.6`)
 - `--with-web` — Build the frontend into the SigNoz image (required for e2e)
+- `--zeus-network-alias` — Give the zeus WireMock container a fixed network alias (e.g. `--zeus-network-alias zeus`) so the SigNoz image build args are deterministic; used by CI to share one image across jobs. Don't flip it between runs of a `--reuse` environment (cached container configs would go stale).
