Part of the L4 LB-IP review (docs/plans/2026-06-03-lb-ip-hygiene-design.md). The 2026-05-30 Traefik .200->.203 move left consumers pointing at the dead .200; this fixes the two in-Terraform ones and replaces the stale networking doc with an accurate registry + a renumber checklist. - woodpecker: forgejo.viktorbarzin.me hostAlias hardcoded 10.0.20.200 (.200:443 refuses TLS now; the next woodpecker apply would re-pin it and break pipeline creation). Now reads the Traefik ClusterIP dynamically via a kubernetes_service data source -- cannot rot on a future renumber and avoids the ETP=Local hairpin trap. - monitoring: ViktorBarzinApexDrift alert summary said "expected 10.0.20.200" -> 10.0.20.203 (cosmetic; alert logic already correct). - docs/architecture/networking.md: rewrote the MetalLB section (it wrongly had KMS on .200, mailserver on a LB IP, "two dedicated") into an accurate 4-IP registry + LB-IP renumber checklist (in-band + out-of-band consumers).
