Media sites get Caddy forward_auth; Authentik scripts cover all proxy providers. BookStack OIDC and Plane admin routing fixes included, plus ops scripts for external auth on valhalla.
Native OAuth/OIDC for Homarr, BookStack, Gitea, and MinIO console; forward_auth with local auth disabled for code-server, uptime, and kopia; Caddy and Authentik scripts updated to match.
Portainer git-stack deploys require stack.env (not .env) in the repo.
Renames all stacks/*/. env → stacks/*/stack.env so Portainer reads
secrets directly from git on each redeploy, making the repo the single
source of truth instead of requiring manual UI sync.
Also fixes the dev stack BOOKSTACK_APP_KEY gap — the key was already
present in the file but missing from Portainer's stored envVars; it
will now be picked up automatically from stack.env on next redeploy.
Updates CLAUDE.md to reflect the new filename convention.
