frankbook: propagate skip-state before restart, PBKDF2 qB seed

The frankbook handler ran port verification even for services the
credential gate skipped, so a parked qbittorrent failed the deploy and
aborted the five arrs. Gate now lives Mac-side (test -s gluetun/env
inside the VM) before restart+verify.

The qB first-boot seed wrote a plaintext WebUI\Password, which qB >= 4.2
ignores (PBKDF2 @ByteArray only), and omitted HostHeaderValidation=false,
which would 401 the LAN forwarder path. Seed now generates the PBKDF2
hash in the VM (python3 hashlib) and sets ServerDomains=* +
HostHeaderValidation=false. Arr categories (lidarr/radarr/tv-sonarr)
pre-created with save_path=/Volumes/COMPLETE/Finished Torrents so any
grab lands in the review dir regardless of wiring details.
