fix: Replace broken netstat liveness probe on coturn with tcpSocket check

coturn started up cleanly every time (all TCP/UDP listeners on 3478/5349 opened fine per logs) but was killed every ~10s because the liveness probe ran "netstat -uln", which doesn't exist in coturn/coturn:latest (sh: netstat: not found) - 36000+ restarts over 88 days for a healthy process. Switched to a tcpSocket probe against the TCP listener coturn already opens on 3478, no in-container tooling required.

 **None** – Alle CRITICAL Tasks erledigt! Nächster Focus: Database Backups

+### Phase 8: Authentik Enrollment/Recovery/MFA Fix (2026-07-27)
+- [x] **matrix-invitation Flow repariert** – fehlende Write/Password/Login-Stages ergänzt, Reihenfolge korrigiert, als Authentik Blueprint (`apps/authentik/authentik-blueprints.yaml`) reproduzierbar gemacht
+- [x] **matrix-invitation-prompt** – 16 fehlerhafte `validation_policies` entfernt (crashten mit `AnonymousUser`/`NoneType`-Fehlern)
+- [x] **Redirect-Stage** – Flow endet jetzt auf `axion1337.chat` statt in der `/if/user/`-Sackgasse (blockiert für `type=external`)
+- [x] **matrix-recovery Flow gebaut** – war komplett leer (0 Stages); Passwort-Reset funktioniert jetzt, verlinkt von der echten Login-Seite
+- [x] **Brand.default_application gesetzt** – behebt mehrere Dead-Ends, wenn eingeloggte User `/` ohne Ziel aufrufen
+- [x] **2FA/Passkey Selbst-Einrichtung** – Links zu `default-authenticator-totp-setup`/`-webauthn-setup` (2FA bleibt optional, `not_configured_action=skip`), dokumentiert unter `axion1337.chat/docs/setup/security.html`
+- [ ] **Backlog**: MAS Custom-Template-Override, um den 2FA/Passkey-Link direkt auf `account.axion1337.chat/account/` anzuzeigen (statt nur über die Doku-Seite) – erfordert Forken der MAS Tera/Askama-Templates via `templates.path`, höherer Aufwand/Risiko, bei MAS-Updates zu pflegen

+| Einladungslink-Fehler: "kein ausstehender benutzer" | Klaus | `AUTHENTIK-CREATE-INVITATION-FLOW.md` | **Fixed (2026-07-27)** — `matrix-invitation` Flow hatte nur Invite+Prompt Stage-Bindings, beide auf `order=0`. Write/Password/Login-Stages fehlten komplett. Live gefixt + als Blueprint (`apps/authentik/authentik-blueprints.yaml`) reproduzierbar gemacht. |

Thore Cimbal	09e4225de5	fix: Replace broken netstat liveness probe on coturn with tcpSocket check coturn started up cleanly every time (all TCP/UDP listeners on 3478/5349 opened fine per logs) but was killed every ~10s because the liveness probe ran "netstat -uln", which doesn't exist in coturn/coturn:latest (sh: netstat: not found) - 36000+ restarts over 88 days for a healthy process. Switched to a tcpSocket probe against the TCP listener coturn already opens on 3478, no in-container tooling required.	2026-07-27 12:00:00 +00:00
Thore Cimbal	c0cb864ca2	docs: Add security.html with Passkey/TOTP self-service setup links Neither Element Web's config.json nor MAS's branding config expose a generic custom-link mechanism, and /if/user/ is blocked for type=external Matrix accounts, so the working Authentik MFA setup flows had nowhere to be discoverable. Added a docs/setup/security.html page, following the exact existing pattern (ConfigMap -> initContainer cp -> nginx), linked from index.html's Support section.	2026-07-27 12:00:00 +00:00
Thore Cimbal	235306a840	fix: Set Brand.default_application so "/" doesn't dead-end at /if/user/ Several dead ends (TOTP/WebAuthn setup after an anonymous visit bounces through login and lands on "/") trace back to Brand.default_application being unset, which falls back to /if/user/ - blocked for type=external Matrix accounts. Set it to the matrix Application. Only changes the bare "/" fallback; explicit URLs like /if/admin/ are unaffected.	2026-07-27 12:00:00 +00:00
Thore Cimbal	e9b24a6d1f	fix: Append redirect stage to TOTP/WebAuthn self-service setup flows 2FA is intentionally optional (not_configured_action=skip on the login flow's validate stage). Users who opt in use the built-in single-stage default-authenticator-totp-setup / -webauthn-setup flows directly, since /if/user/ is blocked for type=external Matrix accounts. Both flows had nothing after the setup stage, so completing enrollment fell back to that same blocked dashboard. Appended the shared redirect stage.	2026-07-27 12:00:00 +00:00
Thore Cimbal	0274f9316c	fix: Build matrix-recovery flow and link it as the login page's recovery flow matrix-recovery existed but had zero stage bindings, and the real login flow (default-authentication-flow, MAS's authentication_flow) never linked to it, so users had no working "forgot password" path. Reused the same default-recovery-* stages the built-in default-recovery-flow already uses successfully, added our redirect stage at the end, and set default-authentication-identification.recovery_flow accordingly.	2026-07-27 12:00:00 +00:00
Thore Cimbal	027f567c8b	fix: Add redirect stage so matrix-invitation ends up at Element, not authentik dashboard After the login stage, the flow had no destination, so it fell back to authentik's own /if/user/ interface - which refuses type=external users (the correct type for Matrix-only accounts), showing "Die Oberflaeche kann nur von internen Nutzern geoeffnet werden". Added a static redirect to https://axion1337.chat as the final stage.	2026-07-27 12:00:00 +00:00
Thore Cimbal	d2bcd90291	fix: Clear erroneous validation_policies on matrix-invitation-prompt The prompt stage had 16 unrelated system policies bound (OOBE, user settings, recovery, etc.), likely from a "select all" slip while configuring it manually. They crash when evaluated in an anonymous enrollment context (AnonymousUser has no group_attributes, etc.), surfacing as opaque errors after form submit. Cleared live and via the blueprint so re-application doesn't reintroduce them.	2026-07-27 12:00:00 +00:00
Thore Cimbal	80714fe901	fix: Repair matrix-invitation enrollment flow via Authentik Blueprint The matrix-invitation flow only had Invite+Prompt stage bindings, both at order=0 (undefined order), missing the Write/Password/Login stages entirely — invited users were never written to the DB. Applied the fix live in-cluster (mirroring the working matrix-enrollment stage chain), and captured it as an Authentik Blueprint (ConfigMap, mounted via blueprints.configMaps) so the flow state is reproducible via GitOps instead of manual admin-UI clicks.	2026-07-27 12:00:00 +00:00
