Add qBittorrent API key authentication (#1143)

[qBittorrent

5.2.0](https://www.qbittorrent.org/news#sun-may-03rd-2026---qbittorrent-v5.2.0-release)
(May 2026) added support for API key-based authentication in addition to
the existing username/password-based authentication.

This commit adds support for qBittorrent API key authentication to
Shelfmark, configurable via environment variable or settings UI. If an
API key is set at the same time as the username/password, API key will
be preferred for authentication.

Requires `qbittorrent-api` 2026.5.3, the version that added the
`api_key` argument, or newer. `403 Forbidden` responses are not retried
with API key authentication because a retry has no chance of succeeding.

Tested end-to-end with my live qBittorrent 5.2.3 instance (WebAPI
v2.15.1).
