Dorian a896ecd431 fix: container security hardening, onboarding viewport scaling, boot screen cleanup
Container security:
- Add --cap-drop ALL + --security-opt no-new-privileges:true to 12 containers
  missing hardening in first-boot-containers.sh (mempool-db, electrumx,
  mempool-api, mempool-web, electrs-ui, btcpay-db, nbxplorer, nostr-rs-relay,
  strfry, tailscale, bitcoin-ui, lnd-ui)
- Mirror same hardening in deploy-to-target.sh for consistency
- Add --read-only + tmpfs to nostr-rs-relay
- Fix filebrowser deploy to include security flags
- Remove duplicate UI image definitions in image-versions.sh
- Separate Jellyfin capabilities (needs FOWNER, exec tmpfs for CoreCLR JIT)
- Harden archy-net creation with existence check and error handling

UI fixes:
- Fix onboarding viewport scaling: all 7 screens now use h-full + max-h-full
  pattern so containers never overflow viewport regardless of padding
- Remove path-option-card wrappers from seed verify inputs, left-justify labels
- Remove batteries/barbarian icons from boot screen (keep bitcoin, cloud, github, save)
