fix(generator-openapi): resolve schemas/params when operationId is missing

[thorthelegend99]

Summary

• fix OpenAPI schema/parameter lookup when operationId is missing
• keep existing lookup by operationId when present
• add fallback lookup by path + method for operations without IDs
• add regression test ensuring no-operationId endpoints get correct schemas and parameter sections

Why

Issue #219 reports that missing operation IDs can lead to incorrect or missing schemas/parameters. The previous lookup used only operationId, which can be undefined across multiple operations.

This change makes schema extraction deterministic for no-operationId specs.

Tests

• corepack pnpm --filter @eventcatalog/generator-openapi format
• corepack pnpm --filter @eventcatalog/generator-openapi test -- --run
• corepack pnpm --filter @eventcatalog/generator-openapi build
