[feat] Add Jobs API infrastructure (PR 1 of 3)

Adds Jobs API types, fetchers, and new API methods without breaking existing code.
This is the foundation for migrating from legacy /history and /queue endpoints
to the unified /jobs endpoint.

New files:
- src/platform/remote/comfyui/jobs/types/jobTypes.ts - Zod schemas for Jobs API
- src/platform/remote/comfyui/jobs/fetchers/fetchJobs.ts - Fetchers for /jobs endpoint
- src/platform/remote/comfyui/jobs/index.ts - Barrel exports
- tests-ui/tests/platform/remote/comfyui/jobs/fetchers/fetchJobs.test.ts

API additions (non-breaking):
- api.getQueueFromJobsApi() - Queue from /jobs endpoint
- api.getHistoryFromJobsApi() - History from /jobs endpoint
- api.getJobDetail() - Full job details including workflow and outputs

Part of Jobs API migration. See docs/JOBS_API_MIGRATION_PLAN.md for details.
