docs: decide Wiki.js (ADR-0014, supersedes 0007) + wiki build issues

ADR-0014 records the decision: Wiki.js replaces Docusaurus for the platform wiki
— the only option meeting both hard requirements (per-group abschotten AND
docs-as-code in git). BookStack ruled out (DB-only, no git). Scope excludes
homelab/docs; neckbeard docs stay in management; content in a dedicated wiki repo
(not a branch, not a monorepo). ADR-0007 set to superseded. #0047 resolved
(decided: Wiki.js). Build issues 0048 (deploy + git storage), 0049 (OIDC + roles/
abschottung: admins write, users read-only), 0050 (theming, colours+logo extracted
from homelab/wiki). #0046 becomes the umbrella. STATUS regenerated; all gates green.
