feat(dataset): update training status api

[Nixieboluo]

What

What changes did you make at a high level?

• Added OpenAPI schemas and route documentation for admin status APIs.
• Added the /admin/status/overview contract for status overview alerts.
• Updated training record responses to include backend-computed actions.
• Updated dataset training query helpers to classify Chunk training states more precisely.
• Updated the collection training detail API to use the shared training lock timeout helper.

How

How did you go about making these changes?

• Reused the existing admin OpenAPI structure under packages/global/openapi/admin/core/status.
• Added explicit training record action enums and included actions on each training record.
• Reused the existing Chunk training lock timeout logic instead of adding a separate timeout rule.
• Kept the alert contract intentionally small: the overview currently reports only Chunk vector training issues.
• Used existing Zod schemas for request and response validation patterns.

Other Notes

What, if anything, hasn't been addressed in these code changes but should be in future changes?

• The overview currently supports only the requested Chunk vector training alert.
• Future status alerts can reuse the same overview response shape when additional operational checks are added.
