* feat(auth): gate OSS signup behind ENABLE_SIGNUP flag
## Problem
The `POST /api/v1/auth/signup` endpoint is unconditionally exposed on
every OSS install. Operators running an invite-only deployment (private
customer instances, staging environments, internal-only tenants) have
no way to disable public account creation without patching the codebase.
The UI also shows the "Sign up" link on `/auth/login` regardless of
whether signup is available, so a locked-down deployment leaves broken
navigation on the login page.
## Fix
Introduce a single `ENABLE_SIGNUP` env var (default `true` — no behavior
change for existing installs) that controls signup end-to-end:
- **Backend** — `api/constants.ENABLE_SIGNUP` is read at module load.
The signup handler returns 403 when it's false. Also exposed on
`GET /api/v1/health` as `signup_enabled: bool` so the UI can mirror
the operator's choice at runtime instead of at bundle-build time.
- **UI** — `getSignupEnabled()` in `lib/auth/config.ts` proxies the
health field, `/api/config/auth` surfaces it to the browser, the
login page conditionally renders the "Sign up" link via a one-shot
`fetch("/api/config/auth")` in `useEffect`, and the middleware
redirects `/auth/signup` → `/auth/login` when disabled (fires before
Next.js can serve the statically-prerendered signup page).
- **Helm** — `config.enableSignup` (default `true`) is rendered into
the ConfigMap as `ENABLE_SIGNUP` so operators can flip it via
`--set config.enableSignup=false` at install/upgrade time.
Fallbacks default to `signupEnabled: true` in every layer so a fresh
install "just works" and matches the backend default.
* address review: rollout on ConfigMap change, cache TTL, no signup-link flash
Four review points on #514:
**P1 — ConfigMap Change Skips Rollout** (`configmap.yaml`). `helm upgrade
--set config.enableSignup=false` updated the ConfigMap but did NOT roll
the api pods, so running processes kept the ENABLE_SIGNUP env from
startup and continued serving the old signup behavior — including
divergence between replicas mid-upgrade.
Fix: add the standard `checksum/config` pod-template annotation on the
four backend Deployments that `envFrom` the ConfigMap (`web`,
`arq-worker`, `ari-manager`, `campaign-orchestrator`). Verified with
`helm template`: all four Deployments share the same checksum on any
given render, and flipping `config.enableSignup` changes the checksum
uniformly so kubectl sees a pod-template diff and rolls all four.
**P1 — Signup Flag Stays Cached (server)** (`ui/src/lib/auth/config.ts`).
Module-scoped cache had no TTL. `revalidate: 300` was passed on the
underlying `fetch()` but the in-memory short-circuit above ran first, so
the value never refreshed until the UI pod restarted.
Fix: add `AUTH_CONFIG_TTL_MS = 5 * 60 * 1000` (matching the fetch
revalidate hint) so the module cache and the Next fetch cache stay in
sync. Backend flag flips propagate within 5 minutes without a pod
restart.
**P1 — Middleware Redirect Uses Stale State** (`ui/src/middleware.ts`).
Same shape as above — a separate module cache with no expiry could keep
redirecting `/auth/signup → /auth/login` after signup was re-enabled, or
keep serving the statically-prerendered signup page after lockdown.
Fix: same `SERVER_CONFIG_TTL_MS = 5 * 60 * 1000` TTL on the middleware
cache.
**P2 — Signup link flash on login page** (`ui/src/app/auth/login/page.tsx`).
Initial `signupEnabled` state was `null`, so `{signupEnabled && ...}`
hid the link on first paint and it popped in after the fetch resolved
— a CLS on every login-page load on stock installs where signup is
enabled.
Fix: initialise the state to `true` (matches the backend default). The
fetch still overrides to `false` when the operator has actually
disabled signup, so the lockdown UI behavior is unchanged; only the
happy-path flash is gone.

* feat: add Helm chart for Kubernetes deployment

* Replace bundled Bitnami subcharts with in-chart manifests on official images
The Bitnami catalog removed all versioned image tags from docker.io/bitnami in
Aug 2025 (old images frozen in bitnamilegacy, maintained catalog now behind a
Broadcom subscription), so the bundled postgresql/redis/minio subcharts no
longer pull. Replace them with plain in-chart manifests built on official
upstream images, keeping the internal/all-in-one path fully self-contained and
free of third-party chart packaging that can disappear:
- internal-postgres.yaml: pgvector/pgvector:pg17 — upstream Postgres plus the
`vector` extension the migrations require. POSTGRES_USER=dograh is the initdb
superuser, so CREATE EXTENSION vector succeeds.
- internal-redis.yaml: redis:7.4-alpine, password-protected, AOF persistence.
- internal-minio.yaml: minio/minio, root creds shared with the app via a single
secret (can't drift); the app auto-creates its bucket.
Service/secret names are unchanged (<rel>-postgresql, <rel>-redisinternal-master,
<rel>-minio) so the app wiring is untouched. Dep passwords are generated once and
persisted across upgrades via lookup. Drop the Chart.yaml dependencies,
Chart.lock, and the `helm dependency` step; the internal manifests gate on the
mode toggles (database.mode=internal, etc.).
Also fixes surfaced by smoke-testing on a live EKS cluster:
- Dockerfile: ship the per-service run_*.sh entrypoints the chart invokes.
- migrate-job: run as a post-install/pre-upgrade hook (the bundled Postgres does
not exist during pre-install) with a wait-for-postgres init container.
- backend env: declare POSTGRES_PASSWORD/REDIS_PASSWORD before the DATABASE_URL/
REDIS_URL that interpolate them (Kubernetes only expands back-references).
- worker liveness probes: pgrep isn't in the slim runtime image; check
/proc/1/cmdline instead (each worker execs its process as PID 1).
- UI: set HOSTNAME=0.0.0.0 so Next.js standalone doesn't bind to the k8s-injected
pod name (which maps to the pod IP only, breaking port-forward/loopback).
Verified end-to-end on EKS 1.36: all pods Ready, migrations applied (pgvector
extension + 27 tables), UI login page and web API served via port-forward.
