POST /api/v1/training/jobs: {"quote":"OWNED_QUOTE_UUID"}
201 for a newly created job; 200 when an accepted quote reuses its job.
Job fields:
id                job UUID
status            native job state, such as awaiting_payment
progress_percent  recorded progress, not an independent quality score
invoice_id        owned native invoice ID or null

completed_at      ISO 8601 timestamp or null
training_session  null or {id, status, step, delivery, verification}

GET /api/v1/training/jobs:
{data: JOB_ARRAY, current_page: INTEGER, last_page: INTEGER, per_page: 50, total: INTEGER}

This is a response-shape reference, not a fabricated live response.
