Flows: one-click automation templates

/v1/flows is a lighter-weight automation layer alongside journeys: GET /v1/flows/templates lists ready-made, one-click templates you install and turn on, rather than a graph you design node by node.

Use flows when you want a standard, well-understood automation (like a birthday message or a re-order reminder) running today; reach for a full journey when you need custom branching, A/B tests, or multi-step timing logic specific to your business.

GET /v1/flows/:id/stats reports performance once a flow is live.
