feat(tasks): add operationId fields to OpenAPI operations for Redoc deep-linking

Promotes operationId fields from trawl_node to devkit. Every operation
in modules/tasks/doc/tasks.yml now has a unique camelCase operationId
(getTaskStats, listTasks, createTask, getTask, updateTask, deleteTask),
enabling stable per-operation deep links in Redoc and compatibility with
API doc generators. Purely additive — no behavior change.

Adds tasks.openapi-operationid.unit.tests.js to assert every operation
has a defined, unique operationId.

Part of infra plan 2026-06-01-trawl-promote-up-followups.md Task 3.
