feat(1d): wire oapi-codegen, generate types/server/client, add 501 stubs — tsk_Kp80nvHV2yLc

- Fix openapi.yaml: quote bearerAuth description that contained unquoted `: ` plain-scalar YAML
- Add server/api/cfg-{types,server,client}.yaml — oapi-codegen v2 config for three split outputs
- Add server/api/gen/gen.go — three //go:generate directives; run `make generate`
- Generate server/api/gen/{types,server,client}.gen.go from the contract (all 15 operations)
- Add github.com/oapi-codegen/runtime v1.4.1 to go.mod (runtime types needed by generated code)
- Add server/internal/httpapi/unimplemented.go — UnimplementedServer satisfies gen.ServerInterface;
  every method writes HTTP 501 + {code,message_zh,message_en} JSON body (no dep on task-1f apierr)
- Update server/cmd/server/main.go — mount /v1 API via gen.HandlerFromMuxWithBaseURL; keep /healthz
- Update server/Makefile — `generate` target now runs `go generate ./...`;
  add `check-generate` CI guard (regenerate + git diff --exit-code)
- Add server/internal/httpapi/unimplemented_test.go — 19 httptest cases covering all 15 API routes
  (501+body), undefined routes (404), and /healthz isolation
