Get legacy ``smart-money`` premium-flow fields — 1-min intervals.

These backward-compatible fields contain aggressor-classified premium;
premium and quote-side classification do not establish opening/closing
status, ultimate ownership, strategy, or information advantage.
Session runs 07:15–16:15 ET. session=current returns today's open session
(or most recent if closed); session=prior returns the previous full session;
date=YYYY-MM-DD returns that day's session.

## Query parameters

- `symbol` string
- `session` string
- `limit` integer
- `date` string, nullable: An explicit ET trading day, YYYY-MM-DD. Overrides `session`; the window is 09:30-16:15 ET on that day. `/api/flow/sessions` lists the days that have data.
