🐛CF_TUNNEL_PASSWORD expose in stdout (docker log)

**Describe the bug**
cloudflared binary/service outputs CF_TUNNEL_PASSWORD to stdout (docker log). Tunnel and connection works just fine, it is about credentials being shown in a log

Cloudflared binary is used as a part of [LinuxServer.io](https://linuxserver.io/) docker container called [docker-swag](https://github.com/linuxserver/docker-swag)

According to information from member of LinuxServer.io [link](https://github.com/linuxserver/docker-swag/issues/568#issuecomment-2925526701), cloudflared binary/service outputs CF_TUNNEL_PASSWORD to stdout (docker log).

**To Reproduce**
1. Use a https://github.com/linuxserver/docker-swag docker container with cloudflared tunnel setup (docker-compose,yaml shown below in Additional context)
2. Run docker-compose up
3. Logs and errors in Logs and errors section

**Expected behavior**
No exposure of CF_TUNNEL_PASSWORD (or any credentials) in stdout (docker log)

**Environment and versions**
- OS: QNAP TS-264D, x86 platform
- Architecture: INTEL
- Version: 2025.05.0
