Start an attachment upload

POST/v1/tasks/{task_id}/attachments/uploads

Phase 1 of the two-phase upload (the SAME presign flow the in-app uploader uses): declares the file and answers a short-lived presigned PUT URL plus the `file_key` to register afterwards. Checked against the plan's file-size and storage allowances. Nothing is attached until phase 2. Supports the optional `Idempotency-Key` header (a replay returns the SAME URL, which may have expired — start a fresh upload instead of replaying old keys).
