### `hello_club_create_transaction`

- The name "hello_club_create_transaction" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
WRITE: create a financial transaction for a member (a charge, or a credit when is_credit is true), e.g. an invoice line or a manual adjustment. This changes the member's amount owing / account credit in the club's books and, with notify_by_email, emails the member. Not idempotent: calling twice creates two transactions. Confirm member, amount and type with the user first. POST /transaction.

### `hello_club_create_member`
