tasks(owncloud-vds-deploy): close 🟢 — 26 GB live + 60s timeout finding

Import complete: 25 044 objs / 26 GB. 99.97% залито rclone'ом (22.2 GB
за ~2.5 ч), оставшиеся 6 файлов (4.04 GB) — 4× .pat ~221 MB + 2× .seospider
1.55+1.7 GB — упали с 502/500 на каждом rclone PUT из-за 60-секундного
HTTP timeout в reva v2.27 datagateway (hardcoded в Go http.Client.Timeout,
не env-configurable).

Workaround: VDS-side curl PUT loopback через throwaway sftp key.
Local network 142 MB/s → 4.04 GB за 28 секунд, все PROPFIND size match.

Wiki: §Gotcha 5 в concepts/ocis-on-vds-deploy-recipe.md документирует
finding + recipe для workaround. Traefik buffering middleware пробован,
не помог (likely vulcand/oxy buffer bug на больших телах) — откатил.
