fix(sse): re-align stream-readiness-policy tests with minimax's openai format

PR #9463 switched minimax/minimax-cn from claude to openai format so images
work. The stream-readiness bump for Claude-format replicas is keyed off the
registry's format field (single source of truth), so minimax legitimately
falls out of that group now. Swap the "Claude-format replica" test fixtures
to agentrouter (still format: "claude") and add explicit coverage that
minimax no longer gets the claude_format_heavy_reasoning bump.

And `tests/unit/v1-models-auth-leak-9320.test.ts:83` shipped a `(k: any)` in a file new enough that `config/quality/eslint-suppressions.json` does not cover it — with `@typescript-eslint/no-explicit-any` set to `error` under `tests/`, that single cast failed the `No new ESLint warnings` gate repo-wide. Same class in `tests/unit/issue-9407-gemini-web-validation-false-positive.test.ts:50` (`(executor as any).testConnection`), which entered at `f1ea77fd04` — `testConnection` is a declared public method on `GeminiWebExecutor`, so that cast was redundant too.

+# Management Authentication
+
+OmniRoute uses four distinct credential families for management access. This guide
+distinguishes them by purpose, scope, and locality.
+
+| Credential              | Scope              | Locality      | Use Case                          |
+|-------------------------|--------------------|---------------|-----------------------------------|
+| Dashboard JWT session   | Full management    | Localhost      | Web dashboard login               |
+| CLI machine-id token    | Full management    | Per-machine    | `omniroute` CLI commands          |
+| Scoped `oma_` token     | Configurable scope | External       | Automation / CI / API access      |
+| Manage-scope API key    | `manage` scope     | External       | Management API calls              |
+
+## Dashboard JWT Session
+
+Generated on dashboard login (`/api/auth/login`). Stored in HTTP-only cookie.
+Valid for the session duration. Cannot be used from external hosts.
+
+## CLI Machine-ID Token
+
+Created by `omniroute auth login` on first use. Stored in `~/.omniroute/auth.json`.
+Used by the CLI for all management operations. Tied to the machine identity.
+
+## Scoped `oma_` Access Token
+
+Created via dashboard or CLI with configurable scopes (e.g., `manage`, `read`).
+Format: `oma_<random-hex>`. Used for programmatic access from external systems.
+
+## Manage-Scope API Key
+
+Standard API key with the `manage` scope enabled. Created in dashboard API Keys page.
+Used for management API calls from external hosts.
+
+## Header Examples
+
+```
+Authorization: Bearer oma_abc123def456
+Authorization: Bearer <standard-api-key-with-manage-scope>
+Cookie: omniroute_session=<jwt-token>
+```
+
+See `docs/reference/API_REFERENCE.md` for endpoint-specific auth requirements.
