Guard null validation errors before Object.keys

When the API returns a validation result with errors: null (which it does for valid documents and for timeout/non-ValidationError failures), this template still evaluates Object.keys(validationResult.errors), causing Vue to throw instead of rendering the modal result. This makes the new Validate action break on every valid document and on timeout-style invalid results; guard with validationResult.errors && ... or normalize errors to {} before rendering.

Useful? React with 👍 / 👎.

Pull request overview

Adds a new “Schema Analyzer” UI modal and supporting backend endpoints to analyze a model’s schema against stored documents, including validation results and per-path observed value type distributions. This complements the existing model/document tooling by surfacing schema/data drift and validation failures directly in the Studio UI.

Changes:

• Add backend actions Model.analyzeSchema and Model.validateDocument plus a shared validation-with-timeout helper, and wire them into authorization.
• Add a new frontend “Analyze Schema” modal in the Models page and a “Validate” modal action in the Document page.
• Add test coverage for schema analysis sampling, nested paths/arrays (depth-limited), and validation timeout/parallelism behavior.
