refactor(ai-gateway): remove model settings

[kilo-code-bot]

Summary

• Remove legacy ModelSettings and VersionedSettings schemas/types from the shared DB schema types.
• Stop decorating OpenRouter and Kilo Auto model metadata with Roo model tool settings.
• Delete the obsolete Roo tool settings helper script while leaving OpenCode and OpenClaw settings intact.

Verification

• No manual testing performed; this removes backend model metadata plumbing with no UI path.

Visual Changes

N/A

Reviewer Notes

• Automated verification was run locally with pnpm format; pnpm typecheck progressed through affected packages but hit the 5-minute tool timeout during unrelated workspace packages.
