docs(admin): fix API key OpenAPI metadata

[kayx23]

Summary

• document self-hosted API key MCP tool access in the Admin API request and response schemas
• rename the try_anyway ReDoc variant title from Original order to Try anyway
• remove internal rollout/review wording from the generated ApiKey.user_name description

Runtime impact

No runtime behavior change. The self-hosted API key handler already accepts and returns allowed_tools; this PR fixes the generated Admin API reference metadata.

Validation

• cargo run -p aisix-core --bin dump-schema
• cargo test -p aisix-admin openapi_
• cargo run -p aisix-admin --bin dump-openapi > /tmp/admin-api.openapi.reviewfix.json
• cargo fmt --check

Summary by CodeRabbit

• New Features

  • API key settings now document an allowed_tools option, including support for allowing all tools with * or leaving the field unset.

• Documentation

  • Clarified API key field descriptions for both request and response formats.
  • Improved guidance on how display names are used in telemetry when omitted.

Warning

Review limit reached

@kayx23, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 35 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Adds allowed_tools (array of strings or null) to the OpenAPI schemas for PublicApiKey and ApiKeyRequest, with wildcard "*" semantics documented. A ReDoc tab label for WhenAllUnavailablePolicy is corrected. The user_name field description is refreshed in the Rust model and JSON Schema to clarify telemetry-only usage.

Changes

OpenAPI and documentation updates

Layer / File(s)	Summary
allowed_tools in OpenAPI schemas and tests crates/aisix-admin/src/openapi.rs	Adds allowed_tools field (array<string> or null) to PublicApiKey and ApiKeyRequest schemas with namespaced tool name and wildcard "*" semantics. Fixes ReDoc tab label for WhenAllUnavailablePolicy second variant from "Original order" to "Try anyway". Extends the existing test to assert allowed_tools presence in both schemas.
user_name doc refresh crates/aisix-core/src/models/apikey.rs, schemas/resources/api_key.schema.json	Replaces outdated CP/API synchronization notes with a concise telemetry-focused description stating "unknown" is used when user_name is omitted.

Check name	Status	Explanation	Resolution
E2e Test Quality Review	⚠️ Warning	The new coverage only inspects merged_openapi() JSON; it never exercises /admin/v1/apikeys through HTTP/store, so it’s spec-level, not E2E.	Add/extend a real CRUD integration test (ideally the etcd round-trip) for allowed_tools on create/update/list/rotate, then keep the OpenAPI assertions.

In `@crates/aisix-admin/src/openapi.rs`:
- Around line 3167-3175: The allowed_tools schema currently permits null but
only documents the omitted case, so clients cannot tell what null means. Update
the OpenAPI/resource model entries for allowed_tools to either narrow the type
to array only or explicitly document the null behavior consistently in both
places, using the surrounding schema definitions in openapi.rs as the reference
points. Make the description public-API accurate and clear about whether null
clears access, matches empty, or is just a server return value.
