fix: use truthy check for intermission filter, add route test

`is True` strict identity fails if the NHL API returns an integer 1
instead of a JSON boolean. A truthy check is safe here since the
Intermission field is always False/0 for non-intermission live games.

Also adds a test that verifies intermission games are separated from
live games in the /scoreboard response.
