feat(openapi): document selftune override audit and clear routes

[nghetien]

Summary

• Add SelftuneOverrideAuditResponseSchema and ClearSelftuneOverrideResponseSchema to src/openapi/schemas.ts, mirroring the field shapes already validated by selftuneOverrideAuditOutputSchema/clearSelftuneOverrideOutputSchema in src/mcp/server.ts.
• Register GET /v1/repos/{owner}/{repo}/selftune/overrides/audit (with its optional limit query param) and DELETE /v1/repos/{owner}/{repo}/selftune/overrides (with its optional confirm:true body) in src/openapi/spec.ts, following the same pattern used for GET .../gate-config/effective.
• Regenerate and commit apps/loopover-ui/public/openapi.json via npm run ui:openapi.
• Add a regression test in test/unit/openapi.test.ts asserting both paths/methods appear in buildOpenApiSpec()'s output and that each response schema's keys match its route's MCP tool output shape.

Closes #9303

Scope

• Backend only: src/openapi/schemas.ts, src/openapi/spec.ts, test/unit/openapi.test.ts, generated apps/loopover-ui/public/openapi.json
• No site/, CNAME, or VitePress changes

Validation

• npx turbo run build --filter=@loopover/engine
• npm run build:mcp
• npm run build:miner
• npm run ui:openapi (regenerated and committed openapi.json)
• npx vitest run test/unit/openapi.test.ts — new + existing assertions pass
• npx vitest run --changed=upstream/main --passWithNoTests — 134 files / 1723 tests passed

Safety

• No secrets, wallets, hotkeys, or trust/reward values touched
• No changes to auth/permission logic — purely additive documentation of existing, already-authenticated routes

Notes

No UI-visible change (schema/doc-only backend change to generated OpenAPI JSON), so no UI Evidence screenshots are applicable.

This pull request changes UI/visual code but its screenshot evidence is incomplete. Every required viewport × theme combination needs its own before/after image pair in a labeled table row (e.g. "Desktop · Light | before | after"). Still missing: Desktop · Dark, Tablet · Dark, Mobile · Dark.

Please resubmit with the remaining rows filled in.

See https://github.com/JSONbored/loopover/blob/main/.claude/skills/contributing-to-loopover/SKILL.md for the exact format and examples. This is an automated maintenance action.
