Import prompts

Add 1-10 validated Prompt Universe candidates to the project as tracked prompts (isTracked: true), as when you add prompts in the app: the project's next scheduled run checks them, within the prompt allowance. Starts no Prompt Universe run and calls no model. THE GATES AND THE ALLOWANCE ARE ALL-OR-NOTHING, THE WRITES ARE NOT: every candidate is checked before anything is written and one refusal refuses the whole batch with 422 prompt_gates_failed and nothing created; the whole batch is then checked against the prompt allowance, and one that does not fit is refused with 403 quota_exceeded and nothing created. Once writing starts each prompt commits on its own and re-checks your prompt quota, so a batch can still stop partway if another write takes the room. Every response - success or failure - carries outcomes, one row per submitted candidate (created / failed / not_attempted); on a partial failure the response keeps the underlying error's own status and code (for example 403 quota_exceeded) and adds created and outcomes, so retry only the rows that are not created. Any topicIds must belong to the same project as the prompt; one that does not is refused with 404 not_found, indistinguishable from a topic id that does not exist. Requires a connection minted with the prompt:draft capability (not the bare write scope), and your own project role must allow the write. Supports Idempotency-Key replay. Returns 404 where the feature is not enabled for the workspace.
