arrproxy: allow unverified email in oauth2-proxy
Authentik hardcodes email_verified=false in the id_token, so oauth2-proxy
rejects the session ("email ... isn't verified") and returns 500 on
/oauth2/callback. Set OAUTH2_PROXY_INSECURE_OIDC_ALLOW_UNVERIFIED_EMAIL=true
so the callback completes; authorization stays enforced downstream via
ak_groups. The oauth2 Deployment already carries configmap.reloader.stakater.com/auto=true
and Reloader is running, so the ConfigMap change rolls the pods automatically.

# Non-secret oauth2-proxy configuration (client_id/secret/cookie_secret come from
# the oauth-credentials Secret). oauth2-proxy is the single auth front for the
# arrstack: it authenticates the UI and the token API against Authentik, and path-
# routes to the arrproxy-ui / arrproxy-api upstreams. /<app>/api is exempted from
# auth (SKIP_AUTH_REGEX) so *arr clients presenting a per-user token reach the api
# directly; the api then validates the token. Everything else requires the oauth
# session and receives identity via X-Forwarded-* / X-Auth-Request-* headers.
