/**
 * A workout entered by hand, end to end against a real Postgres.
 *
 * The web form builds its entry with `buildManualWorkoutEntry` and posts it
 * to `POST /api/workouts/batch`; this suite drives that exact entry through
 * the real route and reads it back through `GET /api/workouts`, then deletes
 * it through `DELETE /api/workouts/{id}`. Pins:
 *
 *   - the entry lands as `MANUAL`, with the start, duration and metres the
 *     form computed, and the list serves it;
 *   - a second submit of the same form is a `duplicate`, not a second row;
 *   - delete removes a hand-entered workout and refuses a synced one.
