chore(deps): update helm chart external-secrets to v2

Authentik's default-authentication-login stage ships with
session_duration: seconds=0, so the SSO session died with the browser.
New blueprint raises it to 30 days for every app on that flow.

FreshRSS runs OIDC through Apache mod_auth_openidc, whose defaults are a
5 minute inactivity timeout and a ~7.5 hour max duration in a non-persistent
cookie. Bumped to a 30 day sliding inactivity window (refreshed on every
request) with a 90 day hard cap, and made the cookie persistent so it
survives a browser restart.

+## Session lifetime
+
+Authentik ships the login stage of `default-authentication-flow` with
+`session_duration: seconds=0`, i.e. the SSO session dies when the browser closes.
+`blueprint-session-duration.yaml` raises this to 30 days for every app that uses
+that flow (FreshRSS, ArgoCD, Vault, Actual Budget, mail).
+
+The expiry is **absolute** — Authentik does not extend a session on activity. A
+sliding window has to come from the application itself; FreshRSS does this via
+`OIDC_SESSION_INACTIVITY_TIMEOUT` (see `freshrss/freshrss-deployment.yaml`), which
+Apache mod_auth_openidc refreshes on every request.
