Add blankpad-host auto-learn skills and memory store

Tracked the harness artifacts accumulated on blankpad (blank@), matching
the existing convention for the --home-dank-* memory stores and the 36
already-tracked managed-skills.

managed-skills (9): authentik-proxy-provider-app-link,
dankclaw-guard-chain-layer-diagnosis, e2e-arr-rawip-reachability-triage,
halogen-kv-pool-fit, lan-client-split-dns-fix, noctalia-reference,
rootless-quadlet-log-retrieval, ssh-key-bootstrap-no-sshpass,
swapfile-resize-safe-ordering.

memories (2 stores): --home-blank-.omp-- (dotfiles_git, handy_lifecycle,
input_permissions) and --home-blank-Projects-serverAppConfig--
(frank_large_quadlet).

Secret sweep before staging: no PEM blocks, no credential literals.
Content is fleet topology/IPs only, same class as the tracked dank stores.
