"""Regression for the 'connected=False but playing=True' stuck-state bug.

After rapid disconnect/reconnect, the library could drop the connection
(TS3 server anti-flood or a hung handshake). The bot then ended up in an
inconsistent state: player.state='playing' but tsClient disconnected.

This test verifies three fixes:
  Bug A — startBot() has a 15s timeout instead of hanging forever on a
          stalled handshake. /start returns a clean 500 instead of blocking.
  Bug B — play/add/etc commands are rejected when the bot is not connected.
  Bug C — the tsClient 'disconnected' handler always clears player state,
          even when connect() never completed (so !this.connected).

We also sanity-check that the bot recovers (can start a fresh cycle) after
a transient failure.
