wiki(concepts): ingest ocis-on-vds-deploy-recipe + entity refresh

New concept page documents the oCIS-on-VDS deploy pattern with the 4
non-obvious gotchas surfaced during owncloud-vds-deploy:

  1. UID mismatch — image ocis-user is 1000, host vitya is 1001 →
     compose `user: "1001:1001"` override (alt chown rejected as orphan-UID)
  2. PROXY_TLS=false — explicit per docs when reverse proxy terminates HTTPS
  3. PROXY_ENABLE_BASIC_AUTH=true — required for WebDAV/LibreGraph API
  4. LibreGraph POST /graph/v1.0/users — only way to create users (no CLI)

Plus decomposedfs storage layout, atomic-revert recipe, backup integration
note. Source: .tasks/owncloud-vds-deploy.md.

entities/vds-kzntsv.md updated: stack table + hostnames + file layout
include owncloud row.

index.md catalog + log.md ingest entry refreshed.
