feat(models): expose all Kilo Auto routing choices

[chrarnoldus]

Summary

Complete autoRouting.models metadata for the public Kilo Auto catalog by adding the two missing entries: Auto Frontier and Auto Small. Auto Efficient, Auto Balanced, and Auto Free were already represented.

• derive Auto Frontier choices from its mode-to-model routing map
• define Auto Small paid and free Gemma targets once and reuse them for runtime resolution and metadata
• deduplicate and sort target IDs, while only exposing models visible in the caller's catalog
• add focused regression coverage for both newly annotated auto models

Verification

• ./node_modules/.bin/oxfmt apps/web/src/lib/ai-gateway/auto-model/index.ts apps/web/src/lib/ai-gateway/auto-model/resolution.ts apps/web/src/lib/ai-gateway/auto-routing-models.ts apps/web/src/lib/ai-gateway/auto-routing-models.test.ts
• git diff --check
• Tests not run locally; CI will handle them as requested.
