Add a persistent "announced" checkbox after each track's Announce button.
The state is stored in a new `announced` column on `show_tracks` and is
auto-set when the Announce button is pressed. The checkbox is also freely
togglable, and announced tracks have their Announce button disabled.
Also fixes .env leakage in test_config.py (pass _env_file=None) and adds
tests for the new DB method, API endpoint, and announce side-effect.

The dashboard's own WS connection was being counted as a bot subscriber,
causing "1 bot connected" with no bots actually present. Now WS clients
send a role ("bot" or "viewer") in the subscribe message. Only bots count
toward the subscriber total. Bot plugins also send a configurable client_id
so the dashboard shows which specific bots are connected.
