trek: trial-deploy TREK group-trip planner behind Authentik (solo eval)

Stand up upstream TREK (mauriceboe/trek:3.0.22, AGPL) as a low-commitment
trial to evaluate the self-hosted group-trip use case before building a
custom app. Solo, single shared instance, Authentik forward-auth.

- stacks/trek: namespace, deployment (pinned, TF-managed, no CI/Keel),
  service 80->3000, ingress_factory auth=required + proxied DNS at
  trek.viktorbarzin.me, TLS. Two proxmox-lvm-encrypted PVCs (SQLite data +
  uploads) -- encrypted per the sensitive-data rule and to avoid the
  SQLite-over-NFS locking hazard.
- Trial secrets posture: ENCRYPTION_KEY auto-generated on the data PVC,
  bootstrap admin in pod logs -- no Vault/ESO. Graduation TODOs documented
  in main.tf + service-catalog (Vault key, app-level SQLite backup, OIDC SSO).
- kyverno: add mauriceboe/* to require-trusted-registries allowlist (the
  policy is Enforce since 2026-05-19 -- also fixed the stale "stays in
  Audit" header comment that said otherwise and misled the deploy).
- Runs free on OpenStreetMap (no paid maps key). Rallly availability-poll
  companion deferred per solo-trial scope.

+| trek | **TRIAL (2026-06-05)** — self-hosted group-trip planner (upstream [TREK](https://github.com/mauriceboe/TREK), `mauriceboe/trek:3.0.22`, AGPL-3.0). Solo evaluation behind Authentik forward-auth (`auth=required`) before deciding build-vs-adopt; covers collaborative trip planning + accommodation records + activities + per-person budget splitting on free OpenStreetMap (no paid maps key). SQLite + uploads on `proxmox-lvm-encrypted` (`trek-data-encrypted` 2Gi, `trek-uploads-encrypted` 5Gi). For the trial only: `ENCRYPTION_KEY` is TREK-auto-generated onto the data PVC and the bootstrap admin (`admin@trek.local`) is printed to pod logs — NO Vault/ESO wiring (graduation TODO: move key to `secret/trek` + ESO, add an app-level SQLite backup CronJob since host file-backup can't read the LUKS PVC, wire TREK↔Authentik OIDC). Pinned image, TF-managed (no CI/Keel). Availability-poll companion (Rallly) deferred. Teardown: `tg destroy` in `stacks/trek`. | trek |
