docs: fix pre-existing broken links surfaced by docs-lint

Problem: docs-lint (added in the wiki-hq reorg) surfaced 126 broken relative
links that predated this session — a container rename, incident/plan docs
that moved into archive/done subfolders without their inbound links being
updated, and a handful of relative-depth bugs in files nested under
containers/archive/ and plans/done/.

Fixes applied, by category:
- 124-authentik.md -> 106-auth-outpost.md (container was renamed; ~40 refs).
- investigations/{2026-04-21-hubris-crash-loop,2026-05-31-authentik-vps-migration}.md
  -> archive/ prefix (both moved to investigations/archive/ previously).
- plans/{2026-06-01-slate-ax-to-sodola-migration,2026-06-04_130000-deprecate-claudio-bot,
  2026-06-25-yuvomi-deployment}.md -> plans/done/ prefix.
- Depth bugs in files nested one level deeper than their siblings assumed
  (investigations/archive/*, knowledge/wiki/containers/archive/*,
  plans/done/*) — corrected relative-path depth.
- Destroyed containers with no surviving page (126-plato) delinked to the
  containers/index.md archaeology row instead of a 404.
- ludo-mini.yaml -> strong.yaml (host was renamed, same physical machine).
- netbird-vps.md (no narrative page exists) -> netbird-vps.yaml (substrate
  record, matching the existing convention for hosts without a wiki page).
- runbook-dpkg-interrupted.md refs -> .agents/skills/runbook-dpkg-interrupted/SKILL.md
  (missed in the phase-4 runbook move because the referencing files used a
  bare filename, not a runbooks/ prefix).
- One dangling forward-reference to a never-written investigation delinked
  to the actual incident record it was describing.

Left alone: two links in knowledge/wiki/containers/101-jellyfin.md into
devops/homelab-authentik-admin/ — an intentional reference to a sibling repo,
not present in this checkout.

Verification: broken-link count 126 -> 2 (real remainder is the cross-repo
reference above); gen-topology.py --check still exit 0; build_host_files.py
still idempotent; all inventory.yaml doc_page targets still resolve.

It therefore does **not** use the file-provider + cert-mirror pattern above:
 
 - Routed via traefik **Docker provider labels** on the `authentik-server` service (`/opt/docker-compose.yml`), not `traefik-dynamic.yaml`.
 - TLS via traefik's own `letsencrypt` resolver (works here because it's a normal HTTP router, not the HostSNI passthrough).

 ### 2026-05-31 — `auth.hubris.network` now served locally on the VPS
-Authentik migrated onto the VPS ([investigation](../../../investigations/2026-05-31-authentik-vps-migration.md)). Unlike the home-backed services above, `auth` is a local container routed via traefik Docker-provider labels with traefik-managed Let's Encrypt — no cert-mirror, no `traefik-dynamic.yaml` router. Admin UI gated by an ipAllowList middleware. Traefik gained a second Docker network (`auth`, `172.30.1.0/24`) to reach it while keeping its DB/Redis isolated from the netbird stack.
