feat(orders): manual order optionally creates a linked project

Add `create_project` flag (default true) to `CreateOrderSchema` and
`CreateOrderData`. When true and `quotation_id` is absent, `createOrder`
creates a `projects` row sharing the order's shared-pool number and
`order_id` link — mirroring the from-quotation flow. The route audits
the new project creation when it occurs.
