fix(secrets): pass OP_LOAD_DESKTOP_APP_SETTINGS through to the op child env

The 1Password secret source builds a minimal allowlisted environment for the
`op read` child process. The allowlist omits OP_LOAD_DESKTOP_APP_SETTINGS, so a
user who exports it (shell, .env, or service unit) sees it silently stripped
before it reaches `op`.

That var is `op`'s documented switch to skip the desktop-app integration probe.
When the 1Password desktop app is installed, `op` probes its settings/socket at
startup *before* evaluating service-account auth. If the desktop app's group
container is wedged (e.g. macOS 'Interrupted system call' on the 1Password group
container), that probe blocks with no timeout, so `op read` hangs indefinitely
even with a valid OP_SERVICE_ACCOUNT_TOKEN present. Setting
OP_LOAD_DESKTOP_APP_SETTINGS=false is the intended escape hatch — but stripping
it means it has no effect on exactly the headless boxes that need it.

Fix: add OP_LOAD_DESKTOP_APP_SETTINGS to _OP_ENV_ALLOWLIST so the documented
var reaches the child. No behavior change when it's unset. Adds a focused test
alongside the existing allowlist test.

Repro: on a machine with a wedged 1Password desktop container + a valid SA
token, `op read` hangs 600s+ without the var and returns in ~4s with it — but
only if it actually reaches the op process, which this allowlist entry ensures.
