CVE-2026-62364: wlc may disclose API tokens to project-configured URLs

wlc could send an unscoped API token to an unintended server when run inside a directory tree containing attacker-controlled project configuration.

If .weblate, .weblate.ini, or weblate.ini defines an API url, and the user supplies a token with WLC_KEY or --key without also pinning the URL, wlc would send the token to the project-configured URL.

Impacted users are those running wlc in untrusted repositories, pull request checkouts, or directories with untrusted ancestor configuration while using WLC_KEY or --key.
