fix: resolve the seven bugs pinned by the test audit

- read [ignored_tags] instead of [ignored_domains], so tag-based ignoring
  actually works
- match ignored tags as whole tags, not substrings ('ipt' no longer matches
  'iptorrents')
- send the login-error notification through the Pushover client instead of
  the non-existent module-level send_message()
- handle an empty torrent list instead of raising IndexError before any
  summary is sent
- tag a new torrent once instead of once per code path
- honour toml_path without DOCKER in AppriseClient
- close replaced log handlers so the file descriptor is released

Also add the missing [telemetry] section to config.toml.example, which
qbit-maid.py requires at startup.

The tests that pinned each bug now assert the fixed behaviour, and the
suite still reports 100% coverage.
