Summary

• Adds an admin Gateway tab for the last 100 model-experiment requests.
• Joins experiment attribution rows to usage, experiment, variant, and variant-version metadata so admins can inspect routing and usage outcomes without reading prompt bodies.
• Adds router coverage for the request-log query shape.

Reviewer Notes

• Prompt content is intentionally not displayed. The table shows only the stored prompt hash/sentinel and attribution metadata.
• This PR is extracted from feat(gateway): route and persist model experiments #3325 so the admin observability surface can land independently.

WARNING

File	Line	Issue
apps/web/src/routers/admin/model-experiments-router.ts	296	createdAt is a raw timestamp(mode:'string') DB value returned directly in the tRPC HTTP body — not normalized to ISO 8601 as required by the repo timestamp serialization rule

SUGGESTION

File	Line	Issue
apps/web/src/app/admin/model-experiments/ModelExperimentRequestsContent.tsx	54	No isError branch — query failures render silently with no user feedback
