bcrypt hashes and most OIDC client secrets contain `$`, so `.env.example`
tells operators to single-quote them or Docker Compose eats the `$`. Docker
Compose then strips those quotes itself when reading `env_file`, and so does
python-dotenv on the `env_file=` path — but podman-compose (1.0.6) forwards
them verbatim. The container receives `'$2b$12$...'`, quotes included, every
bcrypt verify fails, and the logged error blames the operator's hash.
Unwrap one matched pair of surrounding quotes from SECRET_KEY,
AUTH_PASSWORD_HASH and OIDC_CLIENT_SECRET before validating them, so the same
.env works under either container runtime. Only a matched pair is removed: a
value with a single stray quote still reaches the existing validation instead
of being silently patched up, and SECRET_KEY is unwrapped before the 32-byte
OIDC floor is checked so quotes cannot pad a short key past it.
