Viktor Barzin a587f0ee55 t3code: ingress -> devvm dispatch+autopair (retire in-cluster nginx)
stacks/t3code now points the Authentik-gated ingress at the DevVM t3-dispatch
service (Service+Endpoints -> 10.0.10.10:3780) instead of the in-cluster nginx,
which is removed. Per-user routing + session auto-injection now live on DevVM.
Verified: external 302->Authentik; in-cluster vbarzin/emil.barzin->302 (auto-pair
to own instance), unmapped->403.

# TLS secret `tls-secret` (wildcard *.viktorbarzin.me) is auto-cloned into this
# namespace by Kyverno's `sync-tls-secret` ClusterPolicy — no local module or
# cert material needed; the renewal pipeline updates the source and Kyverno
# propagates within seconds.
# === Per-user dispatch + auto-provisioning ===================================
# t3 is single-owner (no in-app multi-user), so each person runs their OWN
# `t3 serve` instance on the DevVM as their own OS user (file perms enforced by
# the uid). A DevVM service `t3-dispatch` (10.0.10.10:3780) routes the single
# hostname t3.viktorbarzin.me by Authentik identity and auto-mints+injects the
# user's t3 session on first visit. Source of truth: /etc/ttyd-user-map. All the
# DevVM-side pieces (t3-serve@ template, reconcile, dispatch, t3-mint, sudoers)
# live in infra/scripts/ and are deployed there (outside TF, like t3-serve and
# terminal-lobby). This stack only owns the K8s edge:
# Traefik (Authentik forward-auth, auth="required") -> Service/Endpoints
# -> 10.0.10.10:3780 (t3-dispatch).
# See docs/plans/2026-06-01-t3-auto-provision-{design,plan}.md.
